▼ Several sensor technologies have been developed and experimented over the last few decades to cater various needs of medical diagnostics. Among these, fiber optic sensors, in particular, Fiber Bragg Grating (FBG) based sensors have attracted considerable attention due to their inherent advantages such electrical passiveness, immunity to Electro Magnetic Interference (EMI), chemical inertness, etc. The present research work focuses on design, development and validation of FBG sensor based devices for measurement of certain healthcare parameters in the context of foot function/gait cycle, cardiac and breathing activity, nostril dominance, hand grip/wrist angle force function, etc. The experimental work presented here emphasizes on the effectiveness and competitiveness of the FBG devices developed, in comparison with standard tools such as Accelerometer, Load cell, Electronic Stethoscope, Electromyogram and Dynamometer. In the field of human balance, stability and geriatrics, two independent FBG devices namely, Fiber Bragg Grating based Stability Assessment Device (FBGSAD) and Optical Sensor Ground Reaction Force measurement Platform (OSGRFP) have been designed, developed and experimented for postural stability assessment and gait analysis respectively. The result of these studies have significant implications in understanding of the mechanism of plantar strain distribution, identifying issues in gait cycles, detecting foot function discrepancies, identifying individuals who are susceptible to falls and to qualify subjects for balance and stability. In the field of ergonomic assessment, Fiber Braggs Grating based Hand Grip Device (FBGHGD) is designed and developed for the measurement of hand grip force which helps in the understanding of several important biomechanical aspects such as neuromuscular system function, overall upper-limb strength, vertebral fracture, skeletal muscle function, prediction of disability, incapacity, mortality and bone mass density (forearm, skeletal sites, spine, hip etc.). Further as an extension of this work, the FBGHGD is used for measurement of force generated by the wrist in different positions of the flexion and extension which relates to the wrist muscle activity and its enactment. In the field of cardiac activity monitoring, a novel, in-vivo, non-invasive and portable device named Fiber Bragg Grating based Heart Beat Device (FBGHBD) is developed for the simultaneous measurement of respiratory and cardiac activities. The work involves designing FBGHBD, validating its performance against traditional diagnostic systems like electronic stethoscope, exploration of its clinical relevance and the usage of FBGHBD in studies involving normal persons and patients with myocardial infarction. The unique design of FBGHBD provides critical information such as nascent morphology of cardiac and breathing activity, heart rate variability, heart beat rhythm, etc., which can assist in early clinical diagnosis of many conditions associated to heart and lung malfunctioning. Further, the scope of this… Advisors/Committee Members: Asokan, S.

Mašinsko inženjerstvo - Motorna vozila / Mechanical engineering - Motor vehicles

motornim vozilima“ razmatrane su mogućnosti unapređenja održavanja pneumatika na motornim vozilima. Opšti naučni cilj disertacije bio je razvoj metode modeliranja uticaja pritiska i opšteg stanja pneumatika na bezbednost saobraćaja, troškove pneumatika, troškove goriva i druge troškove eksploatacije vozila. Značajan cilj i doprinos rada je promocija proaktivnog pristupa održavanju pneumatika za komercijalna vozila a, s tim u vezi, i primena sistema za nadzor pritiska vazduha u pneumaticima (TPMS) kao konceptualnog rešenja koje je blisko konceptualnim rešenjima za ostale sisteme na vozilu, a koji su već poznati i u upotrebi. U okviru disertacije obavljena su istraživanja u SP „Lasta“ A.D., našem najvećem saobraćajnom preduzeću, sa ciljem da se utvrdi da li bi primena TPMS uređaja na komercijalnim vozilima, osim povećane bezbednosti, imala uticaja na povećanje ekonomičnosti eksploatacije. Istraživanja su obuhvatila utvrđivanje stanja pneumatika u SP „Lasta“ A.D., kontrolu i analizu pritisaka vazduha u pneumaticima u SP „Lasta“ A.D. i putna ispitivanja pneumatika u gradskom, prigradskom i međumesnom saobraćaju. Na osnovu analize rezultata istraživanja može se doneti zaključak da je sa gledišta bezbednosti saobraćaja, pogotovu kada se radi o prevozu putnika, održavanje propisanog pritiska vazduha od primarnog značaja. S obzirom da vozači tradicionalno izbegavaju svoje obaveze prema održavanju pneumatika proizvođači pneumatika i vozila izlaz iz ove situacije su potražili u novim tehničkim rešenjima. U doktorskoj disertaciji „Razvoj metodologije za proaktivno održavanje pneumatika na motornim vozilima“ je predstavljen model uticaja pneumatika na troškove eksploatacije vozila. Pošlo se od pretpostavke da odstupanje od propisanog pritiska vazduha u pneumatiku utiče na troškove eksploatacije vozila na četiri načina: povećava intenzitet habanja i smanjuje pređenu kilometražu između dva protektiranja, skraćuje vek spoljne gume, povećava potrošnju goriva (zbog povećanja otpora kotrljanja) i povećani broj iznenadnih otkaza usled separacije protektora ili eksplozije (usled preteranag zagrevanja pneumatika) . Za kvantifikaciju posledica neodgovarajućeg pritiska postavljene su odgovarajuće „krive zavisnosti“, odnosno krive korelacije između odstupanja pritiska od propisanog i promena u veku pneumatika, veku protektora i potrošnje goriva. „Krive zavisnosti“ su integrisane u zajednički model koji je iskorišćen za ocenu predloženih sistema za unapređenje održavanja pneumatika u SP „Lasta“ A.D...

▼ In the oil and gas industry today, continuous wellbore data can be obtained with high precision. This accurate and reliable downhole data acquisition is made possible by advancements in permanent monitoring systems such as downhole pressure and temperature gauges and fiber optic sensors. The monitoring instruments are increasingly incorporated as part of the intelligent completion in oil wells where they provide bottomhole temperature, pressure and sometimes volumetric flow rate along the wellbore - offering the promise of revolutionary changes in the way these wells are operated. However, to fully realize the value of these intelligent completions, there is a need for a systematic data analysis process to interpret accurately and efficiently the raw data being acquired. This process will improve our understanding of the reservoir and production conditions and enable us make decisions for well control and well performance optimization. In this study, we evaluated the practical application of an interpretation model, developed in a previous research work, to field data. To achieve the objectives, we developed a simple and detailed analysis procedure and built Excel user interface for data entry, data update and data output, including diagnostic charts and graphs. By applying our interpretation procedure to the acquired field data we predicted temperature and pressure along the wellbore. Based on the predicted data, we used an inversion method to infer the flow profile - demonstrating how the monitored raw downhole temperature and pressure can be converted into useful knowledge of the phase flow profiles and fluid entry along the wellbore. Finally, we illustrated the sensitivity of reservoir parameters on accuracy of interpretation, and generated practical guidelines on how to initialize the inverse process. Field production logging data were used for validation and application purposes. From the analysis, we obtained the production profile along the wellbore; the fluid entry location i.e. the productive and non-productive locations along the wellbore; and identified the fluid type i.e. gas or water being produced along the wellbore. These results show that temperature and pressure profiles could provide sufficient information for fluid identity and inflow distribution in gas wells.

▼ Designing a fit-for-purpose drilling fluid for high-pressure, high-temperature (HP/HT) operations is one of the greatest technological challenges facing the oil and gas industry today. Typically, a drilling fluid is subjected to increasing temperature and pressure with depth. While higher temperature decreases the drilling fluid?s viscosity due to thermal expansion, increased pressure increases its viscosity by compression. Under these extreme conditions, well control issues become more complicated and can easily be masked by methane and hydrogen sulfide solubility in oil-base fluids frequently used in HP/HT operations. Also current logging tools are at best not reliable since the anticipated bottom-hole temperature is often well above their operating limit. The Literature shows limited experimental data on drilling fluid properties beyond 350?F and 20,000 psig. The practice of extrapolation of fluid properties at some moderate level to extreme-HP/HT (XHP/HT) conditions is obsolete and could result in significant inaccuracies in hydraulics models. This research is focused on developing a methodology for testing drilling fluids at XHP/HT conditions using an automated viscometer. This state-of-the-art viscometer is capable of accurately measuring drilling fluids properties up to 600?F and 40,000 psig. A series of factorial experiments were performed on typical XHP/HT oil-based drilling fluids to investigate their change in rheology at these extreme conditions (200 to 600?F and 15,000 to 40,000 psig). Detailed statistical analyses involving: analysis of variance, hypothesis testing, evaluation of residuals and multiple linear regression are implemented using data from the laboratory experiments. I have developed the FluidStats program as an effective statistical tool for characterizing drilling fluids at XHP/HT conditions using factorial experiments. Results from the experiments show that different drilling fluids disintegrate at different temperatures depending on their composition (i.e. weighting agent, additives, oil/water ratio etc). The combined pressure-temperature effect on viscosity is complex. At high thresholds, the temperature effect is observed to be more dominant while the pressure effect is more pronounced at low temperatures. This research is vital because statistics show that well control incident rates for non- HP/HT wells range between 4% to 5% whereas for HP/HT wells, it is as high as 100% to 200%. It is pertinent to note that over 50% of the world?s proven oil and gas reserves lie below 14,000 ft subsea according to the Minerals Management Service (MMS). Thus drilling in HP/HT environment is fast becoming a common place especially in the Gulf of Mexico (GOM) where HP/HT resistant drilling fluids are increasingly being used to ensure safe and successful operations.

▼ Synthetic gas, syngas, is a popular alternative fuel for the gas turbine industry, but the composition of syngas can contain different types and amounts of contaminants, such as carbon dioxide, methane, moisture, and nitrogen, depending on the industrial process involved in its manufacturing. The presence of steam in syngas blends is of particular interest from a thermo-chemical perspective as there is limited information available in the literature. This study investigates the effect of moisture content (0 ? 15% by volume), temperature (323 ? 423 K), and pressure (1 ? 10 atm) on syngas mixtures by measuring the laminar flame speed in a newly developed constant-volume, heated experimental facility. This heated vessel also broadens the experimental field of study in the authors? laboratory to low vapor pressure fuels and other vaporized liquids. The new facility is capable of performing flame speed experiments at an initial pressure as high as 30 atm and an initial temperature up to 600 K. Several validation experiments were performed to demonstrate the complete functionality of the flame speed facility. Additionally, a design-of-experiments methodology was used to study the mentioned syngas conditions that are relevant to the gas turbine industry. The design-of-experiments methodology provided the capability to identify the most influential factor on the laminar flame speed of the conditions studied. The experimental flame speed data are compared to the most up-to-date C4 mechanism developed through collaboration between Texas A&M and the National University of Ireland Galway. Along with good model agreement shown with all presented data, a rigorous uncertainty analysis of the flame speed has been performed showing an extensive range of values from 4.0 cm/s to 16.7 cm/s. The amount of carbon monoxide dilution in the fuel was shown to be the most influential factor on the laminar flame speed from fuel lean to fuel rich. This is verified by comparing the laminar flame speed of the atmospheric mixtures. Also, the measured Markstein lengths of the atmospheric mixtures are compared and do not demonstrate a strong impact from any one factor but the ratio of hydrogen and carbon monoxide plays a key role. Mixtures with high levels of CO appear to stabilize the flame structure of thermal-diffusive instability. The increase of steam dilution has only a small effect on the laminar flame speed of high-CO mixtures, while more hydrogen-dominated mixtures demonstrate a much larger and negative effect of increasing water content on the laminar flame speed.

▼ The development of an organ preservation system (primarily kidneys and livers, but could be adapted to fit hearts, lungs, and even limbs in the future) that can provide surgeons and doctors with real-time quantitative feedback on the health of the organ would be a significant improvement on current transplant practices. This organ transport system will provide surgeons and doctors the opportunity to make more educated decisions towards whether or not to proceed with organ transplantation. Here, we discuss the use Smart Perfusion's organ preservation system as a platform for determining the optimal perfusion temperature of an organ. Porcine kidneys were procured and perfused with a modified PBS solution on the Vasowave™. While on this organ preservation system, a heart emulating pressure waveform (90/50 mmHg) was generated and sent to the specimen. The pressure response, flow rate, temperature, pH, dissolved oxygen content, and conductivity of the fluid stream were all monitored throughout the duration of experimentation. In addition to inline sensors, IR imaging captured the surface temperature of the organ while on the system. Lastly, the use of a combined heat flux-temperature (CHFT) sensor, previously developed at Virginia Tech, was applied for the first time to monitor and measure local tissue perfusion of an explanted organ. A total of 12 experiments were performed (6 at a set fluid temperature of 15°C, and 6 at 20°C). All system data was collected, statistically evaluated and finally compared against blind histological readings (taken at the termination of each experiment at the hilum and pole) to investigate the effects of temperature on organ vasculature. The results of this experiment indicated that the effects of temperature on explanted kidneys can be affectively measured using a non-invasive bioheat perfusion sensor. Specifically, the lower temperature group of kidneys was measured to have lower perfusion. Furthermore, an enhancement to the CHFT sensor technology (CHFT+) was developed and tested for compliance. A controllable thin filmed heat resistor was added to the CHFT assembly to replace the current convective thermal event. This enhancement improved the measured heat flux and temperature signals and enables autonomy. Also, the thin and semi-flexible nature of the new CHFT+ sensor allows for perfusion measurements to be taken from the underside of the organ, permitting a quantitative measure of pressure ischemia. Results from a live tissue test illustrated, for the first time, the effects of pressure ischemia on an explanted porcine kidney.

► The development of an organ preservation system (primarily kidneys and livers, but could be adapted to fit hearts, lungs, and even limbs in the future)… (more)

▼ The development of an organ preservation system (primarily kidneys and livers, but could be adapted to fit hearts, lungs, and even limbs in the future) that can provide surgeons and doctors with real-time quantitative feedback on the health of the organ would be a significant improvement on current transplant practices. This organ transport system will provide surgeons and doctors the opportunity to make more educated decisions towards whether or not to proceed with organ transplantation. Here, we discuss the use Smart Perfusion's organ preservation system as a platform for determining the optimal perfusion temperature of an organ. Porcine kidneys were procured and perfused with a modified PBS solution on the Vasowave™. While on this organ preservation system, a heart emulating pressure waveform (90/50 mmHg) was generated and sent to the specimen. The pressure response, flow rate, temperature, pH, dissolved oxygen content, and conductivity of the fluid stream were all monitored throughout the duration of experimentation. In addition to inline sensors, IR imaging captured the surface temperature of the organ while on the system. Lastly, the use of a combined heat flux-temperature (CHFT) sensor, previously developed at Virginia Tech, was applied for the first time to monitor and measure local tissue perfusion of an explanted organ. A total of 12 experiments were performed (6 at a set fluid temperature of 15°C, and 6 at 20°C). All system data was collected, statistically evaluated and finally compared against blind histological readings (taken at the termination of each experiment at the hilum and pole) to investigate the effects of temperature on organ vasculature. The results of this experiment indicated that the effects of temperature on explanted kidneys can be affectively measured using a non-invasive bioheat perfusion sensor. Specifically, the lower temperature group of kidneys was measured to have lower perfusion. Furthermore, an enhancement to the CHFT sensor technology (CHFT+) was developed and tested for compliance. A controllable thin filmed heat resistor was added to the CHFT assembly to replace the current convective thermal event. This enhancement improved the measured heat flux and temperature signals and enables autonomy. Also, the thin and semi-flexible nature of the new CHFT+ sensor allows for perfusion measurements to be taken from the underside of the organ, permitting a quantitative measure of pressure ischemia. Results from a live tissue test illustrated, for the first time, the effects of pressure ischemia on an explanted porcine kidney. Advisors/Committee Members: Diller, Thomas E.

▼ Feldspar minerals are framework aluminosilicates that comprise approximately 60 percent of the Earth's crust. The elastic and thermodynamic properties of this important mineral group are needed for the interpretation of seismic wave velocities, for understanding cation partioning patterns and for the determination of phase boundaries and reactions involving feldspars in the Earth's crust. Until recently, no systematic approach has been applied to describe the structural behavior of feldspars as a function of pressure, temperature and composition. In this thesis, high-pressure and high-temperature X-ray diffraction data were collected for feldspars over a range of compositions which has led to the development a structural model that allows one to predict the structural evolution of feldspars at depth in the Earth's crust. Specifically, the equations of state have been determined for two plagioclase feldspars (An20 and An78) with different states of Al/Si ordering using single-crystal X-ray diffraction. This study has shown that the introduction of Al,Si disorder into plagioclase structures at constant composition softens the structure by 4(1)% for An0, 2.5(9)% for An20 and is essentially zero for An78 compositions. The effect of pressure on the structure of an ordered An20 was also determined up to 9.15 GPa using single-crystal X-ray diffraction and it was found that the dominant compression mechanism involves tilting of the AlO4 and SiO4 tetrahedra. Similarly, high-temperature single-crystal X-ray diffraction data collected from an ordered An26 plagioclase and powder X-ray diffraction collected on a suite of Na-rich plagioclases that were refined using the Rietveld method indicate that the major structural response to increased temperature involves tilting of the tetrahedra. Building on ideas originally proposed by Dr. Helen Megaw, the changes in the conformation of the tetrahedral framework of feldspars can be described in terms of four distinct tilt systems of rigid tetrahedra. This model demonstrates that the fundamental reason for the observed anisotropy and volume change of feldspars lies in the topology of the tetrahedral framework with the greatest contribution attributed to tilt systems 2 and 3.

▼ Fermentation under non-conventional conditions has gained prominence in the last years, due to the possible process improvements. Food fermentation under sub-lethal pressures is one of such cases, and may bring novel characteristics and features not only to fermentative processes, but also to the final food products. In this work, yogurt production was used as a case-study of this approach and the effect of variation of both pressure (10-100 MPa) and temperature (25-50 ºC) during fermentation was studied. Initially, a preliminary study was performed aiming the development of strategies to reduce the experimental time and resources during the work. Then, a kinetic study was conducted, evaluating lactic acid production and lactose consumption over fermentation time. Fermentative rates were highly dependent on the fermentation conditions used, with the increase of pressure slowing down yogurt fermentation and higher rates achieved at 43 ºC. But, interesting features were obtained at 10 MPa, where pH variation profiles were similar to those of atmospheric pressure (0.1 MPa) at almost all temperatures tested. In particular, fermentation at 10 MPa/43 ºC presented the optimal conditions, where yield and efficiency of lactic acid production during fermentation were improved relatively to fermentation at 0.1 MPa – 1.40 gP gS -1 of yield and 75 % of efficiency at 10 MPa against 0.79 gP gS -1 and 40 % at 0.1 MPa, respectively. In addition, the final yogurts produced were analyzed regarding their microbiological and physical properties, and differences were observed between yogurts. In the case of starter cultures, it was found that their growth is affected by the fermentation conditions used during yogurt production: fermentations at 35 and 43 ºC lead to final microbial counts higher than 8.00 log10 (CFU g-1), while counts between 3.00 and 6.50 log10 (CFU g-1) were obtained after the fermentations at 50 ºC. Comparing both starter cultures, Streptococcus thermophilus was more sensitive to the combination of high temperature and high pressure than Lactobacillus bulgaricus. Regarding physical properties of the gel network, both syneresis and texture were influenced by the variations of the fermentation conditions. In this case, the yogurts fermented at 10 MPa presented characteristics more similar to the yogurts produced at 0.1 MPa (syneresis levels similar to control samples and a firm texture without being excessive). A comparative metabolomic study was performed to analyze the metabolites present on the yogurts produced. Several differences were observed in the metabolite accumulation, including aromatic compounds, organic acids and alcohols, all products of yogurt fermentation. The main difference was verified on the compounds responsible for butter-like flavor in yogurt, with diacetyl being present in higher amounts on 0.1 MPa yogurts, while higher amounts of acetoin were obtained on 10 MPa yogurts. These differences can be reflected in the sensorial perception of yogurts, where 10… Advisors/Committee Members: Delgadillo Giraldo, Ivonne (advisor), Jorge Manuel Alexandre Saraiva (advisor), Gomes, Ana Maria Pereira (advisor).

▼ The research of this dissertation has focused on the volumetric properties of electrolyte solutions, including seawater, across wide ranges of temperature and concentration. The volume and compressibility are inherently useful as physical chemical properties of electrolyte solutions. They are directly related to the density and sound speed of a solution; thus, they are important for studying physical processes and properties in the ocean, including mixing, sound transmission, and water mass stability. Possibly of greater significance, however, is the volume’s role as a thermodynamic variable that guides chemical systems into equilibrium. By analyzing the volume properties of electrolyte solutions over wide ranges of temperature and concentration, the results of this dissertation can be used to study the physical chemistry of the ocean, from the surface to depth, geothermal waters, estuaries, rivers, and industrially treated waters. In the first part of my thesis work, I have examined the volume properties of electrolytes, including seawater and rare earth elements from measurements of the density and sound speed. Using the volume parameters, I evaluated two different chemical computational models to estimate the density and compressibility of mixed solute solutions on a composition basis over a wide range of temperature and concentration. The results have applicability for examining brines to fresh waters, and can be used in industrial applications of seawater, such as desalination and other chemical engineering treatments. In the second part of my dissertation, I make use of the volume as a thermodynamic variable to estimate the effect of pressure on a chemical equilibrium reaction. The partial molal volume (V) is the pressure partial derivative of the Gibb’s Free Energy (G) and it can be used to examine various equilibrium reactions, including ion association, acid dissociation, and mineral solubility. I have examined the volume change for the dissociation of a Tris buffer, to predict the effect of pressure on its dissociation. The Tris buffer is used in ocean studies to calibrate electrodes and indicators for measuring the pH of ocean waters, and knowledge of the effect of pressure on the buffer’s dissociation reaction will be useful for the in-situ calibration of pH sensors. The results of this dissertation can contribute to: 1) defining the thermodynamic state variables of various electrolyte solutions, including seawater, rare earth elements, and the Tris buffer with volume and compressibility measurements; 2) enabling the prediction of physical chemical properties of mixed-solute solutions of varying composition; and 3) enabling the prediction of the effect of pressure on chemical equilibria.

V magistrski nalogi je prikazana tehnologija izdelave miniaturnega vlakenskega tlačnega senzorja, ki je zaradi preprostih in malo številčnih procesnih korakov primerna za ceneno serijsko proizvodnjo. Tehnologija temelji na uporabi posebnega senzorskega vlakna, selektivnem jedkanju in mehansko-kemični obdelavi vrha optičnega vlakna. Celoten proizvodni proces je ob minimalnih nastavitvah in prilagoditvah parametrov izdelave primeren za izdelavo poljubno občutljivih tlačnih senzorjev. V sklopu naloge sta poleg tlačnega senzorja predstavljena še dva tipa miniaturnih kombiniranih tlačno-temperaturnih vlakenskih senzorjev, ki imata visoko tlačno občutljivost in široko temperaturno področje. V obeh primerih senzor predstavlja interferometer, ki je zgrajen iz dveh zaporednih Fabry-Perot resonatorjev. V prvem primeru je senzor izdelan na vrhu dovodnega enorodovnega vlakna. Zanj je narejen matematični model za izračun odbitega svetlobnega toka, ki potuje skozi dve oz. tri polprepustna zrcala. V drugem primeru je senzor izdelan na vrhu mnogorodovnega vlakna, ki senzorju omogoča cenovno ugodnejše signalno procesiranje in večjo robustnost.

In presented M.Sc. thesis the technology and design of miniature fiber-optic pressure sensor was demonstrated. The production process consists of few steps that are suitable for low cost serial production. The technology is based on use of a special custom made optical fiber, selective etching, and micromachining of an optical fiber end. The production process is appropriate for design of pressure sensors having arbitrary pressure sensitivities, achieved with minimal adaptation of production parameters. Furthermore, thesis presented two different types of dual parameter sensors for simultaneous measurements of pressure and temperature. Sensors demonstrate high pressure sensitivity and broad temperature range. In both cases, interferometric sensor consists of two Fabry-Perot resonators in series at optical lead-in fiber end. In the first case, the sensor is integrated into a standard lead-in single-mode fiber. Conditions in single mode sensors are in detail described with mathematical model. In the second case, the sensor is integrated into a standard lead-in multimode fiber that in contrast to single mode sensor presents the possibility for reduction of signal processing costs.

▼ An emerging waste management trend in the United States is to operate a landfill as a bioreactor. Effective moisture addition is the key to operating a bioreactor and this is most commonly accomplished using leachate recirculation. Vertical wells are relatively common in retrofit landfills. Vertical wells were installed to operate cell 1 and part of cell 2 as a bioreactor at the New River Regional Landfill (NRRL). Several lessons were learnt from the injection trials that prompted this research. This dissertation was organized into three main research objectives. The first objective was to evaluate the performance of a unique method for adding leachate in the landfill by burying the vertical wells. A cumulative volume of 8431 m3 (2.2 million gallons) of leachate was recirculated intermittently in the buried vertical well clusters over the period of 153 days. Leachate was injected under a pressure higher than the screen length of the vertical wells in the cluster without causing any surface seeps on the landfill. The average flow rate varied substantially from 9.3times10-4 to 14.2times10-4m3/sec (14.7 to 22.5 gpm) with increase in the well depth of the vertical well cluster from 6 to 9m. The entire screen length of the vertical wells in a cluster was not getting used during the initial period of leachate re-circulation due to a significant reduction in pressures between the first and the last vertical well in the cluster. Comparison of field test results indicated that the average leachate flow rate of the buried vertical well clusters was almost the same or higher compared to the conventional vertical wells. The second objective was to examine the temporal and spatial impact of leachate recirculation into buried vertical wells on the pore water pressure in the surrounding waste was investigated due to concerns with slope stability. The piezometers showed a steady increase in pore pressure in the surrounding waste over time and would continue to increase until the leachate addition in the well reached a steady state. Even though large pressures were present in the bottom of a buried vertical well during leachate injection it significantly reduced in the surrounding waste. Even though the hydrostatic head increased with the depth of the vertical well during leachate injection, the pore water pressure in the waste did not increase proportionally indicating that the permeability of waste was lower in the deeper sections of the landfill. Also there was a significant reduction in the pore water pressure in just few meters below the bottom of the buried vertical well which indicates the anisotropic nature of the waste. Thus, the stability of the landfill due to leachate addition in the buried vertical well may not be a concern if a suitable distance is maintained from the side slope of the landfill. The third objective was to evaluate the effect on landfill settlement resulting from moisture addition using vertical wells. The surface of the landfill settled an average of 2.48m (8.1ft) or 11.3% of the initial height in… Advisors/Committee Members: Townsend, Timothy G. (committee chair), Annable, Michael D.

▼ The Multilayer Transient Test is a well-testing technique designed to determine formation properties in multiple layers, and it has been proved effective during the past two decades. To apply the Multilayer Transient Test, a combination of rate profiles from production logs and transient rate and pressure measurements are required at multiple surface rates. Therefore, this method can be time consuming and may involve significant errors due to inaccurate transient flow rate measurements. A new testing approach is proposed after realizing the limitations of the Multilayer Transient Test. The new testing approach replaces the transient flow rate measurement with transient temperature measurement by using multiple temperature sensors. This research shows that formation properties can be quantified in multiple layers by analyzing measured transient temperature and pressure data. A single-phase wellbore/reservoir coupled thermal model is developed as the forward model. The forward model is used to simulate the temperature and pressure response along the wellbore during the transient test. With the forward model, this work proves that the transient temperature and pressure are sufficiently sensitive to formation properties and can be used for multilayer reservoir characterization. The inverse model is formulated by incorporating the forward model to solve formation properties using nonlinear least-square regression. For the hypothetical cases, the proposed new multilayer testing method has successfully been applied for investigating formation properties in commingled multilayer reservoirs. Layer permeability, damaged permeability, and damaged radius can be uniquely determined using single-point transient pressure data and multipoint transient temperature data at appropriate locations. Due to the proposed data acquisition scheme, only one surface flow rate change is needed to implement this testing approach, which significantly reduces the test duration compared to the standard multilayer transient testing approach using a series of flow rate changes. Of special interest, this is the first test design that shows promise for determination of the damaged radius, which can be useful for well stimulation design. In addition, temperature resolution, data noise, and data rate impacts have been studied along with a data filtering approach that enable selection of suitable pressure and temperature sensor technologies for applying the new testing method.

▼ Fuel flexibility in gas turbines is of particular importance because of the main fuel source, natural gas. Blends of methane, ethane, and propane are big constituents in natural gas and consequently are of particular interest. With this level of importance comes the need for baseline data such as laminar flame speed of said fuels. While flame speeds at standard temperature and pressure have been extensively studied in the literature, experimental data at turbine-like conditions are still lacking currently. This thesis discusses the theory behind laminar flames; new data acquisition techniques; temperature and pressure capability improvements; measured flame speeds; and a discussion of the results including stability analysis. The measured flame speeds were those of methane, ethane, and propane fuel blends, as well as pure methane, at an elevated pressure of 5 atm and temperatures of 298 and 473 K, using a constant-volume, cylindrical combustion vessel. The current Aramco mechanism developed in conjunction with National University of Ireland Galway compared favorably with the data, while the literature data showed discrepancies at stoichiometric to rich conditions. An in-depth flame speed uncertainty analysis yielded a wide range of values from 0.5 cm/s to 21.5 cm/s. It is well known that high-pressure experiments develop flame instabilities when air is used as the oxidizer. In this study, the hydrodynamic instabilities were restrained by using a high diluent-to-oxygen ratio. The thermal-diffusive instabilities were inhibited by using helium as the diluent. To characterize this flame stability, the Markstein length and Lewis number were calculated for the presented conditions. The resultant positive Markstein lengths showed a low propensity of flame speed to flame stretch, while the larger-than-unity Lewis numbers showed the relatively higher diffusivity of helium to that of nitrogen.

▼ Knowledge of flammability limits is essential in the prevention of fire and explosion. There are two limits of flammability, upper flammability limit (UFL) and lower flammability limit (LFL), which define the flammable region of a combustible gas/vapor. This research focuses on the flammability limits of hydrogen and its binary mixtures with light hydrocarbons (methane, ethane, n-butane, and ethylene) at sub-atmospheric pressures. The flammability limits of hydrogen, light hydrocarbons, and binary mixtures of hydrogen and each hydrocarbon were determined experimentally at room temperature (20?C) and initial pressures ranging from 1.0 atm to 0.1 atm. The experiments were conducted in a closed cylindrical stainless steel vessel with upward flame propagation. It was found that the flammable region of hydrogen initially widens when the pressure decreases from 1.0 atm to 0.3 atm, then narrows with the further decrease of pressure. In contrast, the flammable regions of the hydrocarbons narrow when the pressure decreases. For hydrogen and the hydrocarbons, pressure has a much greater impact on the UFLs than on the LFLs. For binary mixtures of hydrogen and the hydrocarbons, the flammable regions of all mixtures widen when the fraction of hydrogen in the mixture increases. When the pressure decreases, the flammable regions of all mixtures narrow. The applications of Le Chatelier?s rule and the Calculated Adiabatic Flame Temperature (CAFT) model to the flammability limits of the mixtures were verified. It was found that Le Chatelier?s rule could predict the flammability limits much better than the CAFT model. The adiabatic flame temperatures (AFTs), an important parameter in the risk assessment of fire and explosion, of hydrogen and the hydrocarbons were also calculated. The influence of sub-atmospheric pressures on the AFTs was investigated. A linear relationship between the AFT and the corresponding flammability limit is derived. Furthermore, the consequence of fire relating to hydrogen and the hydrocarbons is discussed based on the AFTs of the chemicals.

Tехничке науке – Eлектротехника и рачунарство / Technical sciences – Electrical and computer engineering

Примена сензора је у наглом порасту у свим областима живота и рада. Све је већи број физичких, али и других (хемијских, биолошких) величина које је потребно мерити, уз растуће захтеве у погледу функционалности и мерних перформанси уређаја и уз истовремено смањење димензија, цене и потрошње енергије. Појавом микроелектромеханичких технологија и система (МЕМС), почело је ново раздобље у развоју сензора, које и данас траје. Сензори које је тим технологијама могуће реализовати по карактеристикама су упоредиви или бољи од конвенционалних, а малих су димензија и погодни за јефтину масовну производњу. Конвергенцијом сензорских, рачунарских и комуникационих технологија настали су интелигентни инструменти и дистрибуирани сензорски системи, чиме се достиже нови ниво функционалности и перформанси. Научна истраживања у области сензора, мерних метода и инструмената су због тога веома актуелна и имају све израженији мултидисциплинарни карактер.

Atualmente, existe no mundo a necessidade de buscar alternativas aos combustíveis fósseis por fontes renováveis para a produção de energia. O gás natural possui vantagens significativas em relação a outros combustíveis fósseis, em especial pela redução nas emissões atmosféricas provenientes da sua combustão. O uso do metano presente no biogás é uma alternativa renovável ao uso do gás natural nas suas diversas aplicações, incluindo gás natural veicular. Para separação de metano, membranas têm recebido grande atenção devido às diversas vantagens, tais como eficiência energética na operação e baixo impacto ambiental com relação à outras tecnologias. Membranas poliméricas de poli (fluoreto de vinilideno) (PVDF) e polissulfona (PSf) foram sintetizadas através do método de inversão de fases. A realização de ensaios de permeação sob uma faixa de pressão de operação entre 2 e 5 bar, e sob uma faixa de temperatura de operação entre 20 e 45°C, e a análise da morfologia das membranas através de microscopia eletrônica de varredura em amostras das membranas, permitiram que fossem identificados os mecanismos de transporte atuantes nas membranas poliméricas. Os mecanismos de transporte contribuíram para a investigação e o entendimento da influência dos parâmetros de operação (temperatura e pressão) sobre a permeabilidade e a seletividade na separação de gases (CO2/CH4) nas membranas poliméricas. As membranas de poli (fluoreto de vinilideno) (PVDF) apresentaram elevada permeabilidade para ambos os gases em todas as pressões (2 a 5 bar) e temperaturas (20 a 45°C) estudadas, porém não se mostraram atraentes para esta aplicação devido à baixa seletividade na separação de gases, enquanto que as membranas de polissulfona (PSf) demonstraram boas perspectivas para esta aplicação, devido a uma melhor relação entre permeabilidade e seletividade. O incremento da pressão dentro da faixa estudada (2 a 5 bar) resultou em menores fluxos de permeado para o gás CO2, e fluxos de permeado constantes e por vezes maiores para o gás CH4. O incremento da temperatura aumentou o fluxo de permeado de ambos os gases.

Currently, there is a need in the world to substitute fossil fuels for renewable sources in the energy production. Natural gas has significant advantages over other fossil fuels, in particular the reduction in atmospheric emissions from their combustion. The use of methane, present in biogas, is a renewable alternative instead of using natural gas in its various applications, including as an alternative energy for vehicles. Within this context, polymeric membranes have received great attention due to several advantages, such as energy efficiency in operation and low environmental impact regarding to other technologies. Polymeric Membranes of poly (vinylidene fluoride) (PVDF) and polysulfone (PSf) were synthesized by the phase inversion method. Permeation testing under a range of operating pressure between 2 and 5 bar, and under a range of operating temperature between 20 and 45 °C, together with morphology analysis by scanning electron…

▼ Part 1 The viscosity of silicate melts is a fundamental physical property that determines the mobility and transport behaviour of magma on the surface and in planetary interiors. The viscosity of liquid fayalite (Fe2SiO4), the Fe-rich end-member of the abundant upper mantle mineral olivine, was determined up to 9.2 GPa and 1850 °C using in situ falling sphere viscometry and X-ray radiography imaging. The viscosity of liquid fayalite was found to decrease with pressure both along the melting curve and an isotherm, with temperature having very little influence on viscosity at high pressure. This work is the first to determine the viscosity of a highly depolymerized silicate melt at high pressure as only recent advances in experimental techniques have allowed the difficulties associated with studying depolymerized liquids at high pressure to be overcome. The results are in contrast with previous studies on moderately depolymerized silicate melts such as diopside and peridotite which found viscosity to initially increase with pressure. In accordance with recent in situ structural measurements on liquid fayalite, the viscosity decrease is likely a result of the increase in Fe-O coordination with pressure. The results show that the behaviour of silicate melts at depth is strongly dependent on the melt structure and composition. Part 2 The magnitude of the thermal anomaly at hotspot locations has a fundamental influence on the dynamics of mantle melting and therefore has an important role in shaping the surface of our planet. The North Atlantic Igneous Province (NAIP) is the surface expression of a major mantle plume and is unique in the fact that it has a complete magmatic history. The highest 3He/4He volcanic rocks on Earth are found in the early NAIP picrites of West Greenland and Bafin Island and high 3He/4He rocks are still erupted on Iceland today. However, the relationship between 3He/4He and mantle plumes has remained enigmatic. The main aim of this work is to use the ideal opportunity provided by the NAIP to investigate the relationship between temperature, mantle melting dynamics and helium isotopes within a mantle plume. The magmatic temperatures of a suite of picrites and primitive basalts spanning the spatial and temporal range of the NAIP was determined using traditional olivine-melt thermometry, a forward mantle melting model and the newly developed Al-in-olivine thermometer. This study is the first to provide a detailed petrologic approach to investigating the mantle temperature of the NAIP throughout its magmatic history and is the first to compare all three techniques in detail. The Al-in-olivine thermometer was found to be the most robust proxy for mantle temperature. The early stage of volcanic activity in the NAIP is associated with the arrival of the ancestral Iceland plume head and resulted in a uniform temperature anomaly with Al-in-olivine temperatures 250-300° above that of ambient MORB across an area 2000 km in diameter. In addition, the temperature of the plume is shown to have been subject to…

▼ Leveraging the superior properties of silicon carbide (SiC) for harsh environment and demanding applications, a series of SiC capacitive pressure sensors have been developed and characterized for use up to 550°C. To address the related high-temperature-capable metallization need, a thermally stable Ti/TaSi₂/Pt Ohmic contact was developed for heavily-doped polycrystalline 3C-SiC films used in the construction of the pressure sensors. These contacts showed very good linearity with specific contact resistance as low as 5.7´10^-6 O-cm² without thermal annealing following metal sputtering. The metallization demonstrated robustness after being subjected to an aging test in air at 550°C for 1000 hours. Specific contact resistance remained stable in the range of ~10^-5 O-cm². A finite element analysis tool was used to model diaphragm displacement and study the thermal mismatch stress effect on sensor behavior for different substrates. The simulation confirmed that dielectric constant variation with temperature, rather than thermal expansion mismatch stress, dominated the capacitance change. SiC Sensors were fabricated on both SiC and Si substrates, and characterized at room temperature and 500°C. Both sets of sensors demonstrated similar performance, which were in agreement with the simulation results. The capacitance versus pressure behavior of fabricated capacitive SiC pressure sensors were characterized from 2.1 MPa (300 psi) to 8.3 MPa (1200 psi) and for temperatures up to 550°C. The measurement results were found to be in agreement with the analytical calculations. Comparison tests were also performed for sensing capacitance gap sizes and operating modes (i.e., small deflection and touch mode of the diaphragm). Sensors with 0.5 µm sensing capacitance gap showed improved sensitivity, while allowing for smaller diaphragms for a given pressure. With respect to operating modes, contact mode sensors exhibited superior performance to small deflection mode sensors in terms of sensitivity, nonlinearity and resolution. Thus, for a single sensor on a SiC substrate with 0.5 µm gap and 70 µm diaphragm radius, a repeatable performance of 0.06 fF/Pa (0.39 pF/psi) sensitivity and 2.0% nonlinearity was obtained at 550°C for contact mode operation.

▼ The increase in air traffic has contributed to increase in emission of a number of volatile organic compounds (VOC’s) and particulate matter (soot). These emissions cause significant environmental damage and the inhalation of particulate matter is hazardous to human health. The key element to reducing emissions is in interpreting the combustion chemistry of aviation fuels. The coupling of detailed combustion chemical kinetics and computational fluid dynamics will provide insight into the effect of the fuel composition on pollutant formation. Jet fuels consist of several hundreds of chemical components and building a detailed chemical kinetic model for wide spread predictive use with computational fluid mechanics is probably impossible. An alternative approach is to choose surrogate fuel components that replicate the parent fuel in both physical and chemical characteristics and consequently can provide a more general and thereby practical fuel model. In the present work, the combustion chemistry of the aromatic surrogate fuel components of jet fuels, n-propylbenzene, 1,3,5-trimethylbenzene and m-xylene was investigated. This project was executed in three correlated approaches 1) Development of an experimental database: Experiments were conducted in the High Pressure Single Pulse Shock Tube on m-xylene, 1,3,5-trimethylbenzene and n-propylbenzene for pressures of 20 – 60 atm, for temperatures ranging from 900 – 1800 K and for different equivalence ratios ɸ = 0.5, 1, 2 and ∞. 2) Quantification of VOC’s and polycyclic aromatic hydrocarbons (PAHs): The products formed from the oxidation of these aromatic fuels were analyzed both qualitatively and quantitatively by using GC and GC/MS. Several volatile organic compounds (VOC’s) and polycyclic aromatic hydrocarbons (PAHs) were also measured in the products. Measurement of PAHs is important because chemical growth of PAHs leads to the formation of soot. 3) Development of a chemical kinetic models: The chemical kinetic models for the oxidation of n-propylbenzene, 1,3,5-trimethylbenzene and m-xylene were developed based on the experimental results obtained in steps 1 and 2. These models will be used to develop comprehensive chemical kinetic model for combustion of jet fuels. Advisors/Committee Members: Brezinsky, Kenneth (advisor).
