▼ The use of magnetorheological fluids (MRF) is presented as an alternative to overcome some of the problems encountered in the drilling and completion of a well. The magnetorheological fluids can modify their rheological properties instantaneously under the influence of a magnetic field. In this thesis, MRF consist of a base fluid, magnetizable particles and a polymer that supports the particles. The magnetizable particles align in the direction of the magnetic field, thus modifying the rheology of the mixture. Because of this characteristic, the use of this fluid can have advantages in controlling fluid losses while drilling in narrow operating windows, to provide a tunable sealing mechanism that could work as a packer, to provide a set-on-demand slurry, and as a novel mechanism for releasing stuck pipe. Using existing correlations for estimating the pressure drop in pipes and annuli and a model to estimate the yield stress of the fluid based on concentration of the magnetizable particles and the magnetic field strength, it is possible to determine the pressure drop caused by the fluid behavior when in presence of a magnetic field. The rheological properties of the MRF are measured in a rotational rheometer with two electromagnets attached to the measuring cup. The magnetic field is varied, and the shear stress and viscosity are measured at different shear rates and magnetic field strengths. The settling ratio is evaluated comparing different carrier fluids, magnetizable particle concentration and use of surfactants. On an experimental setup, different MRF samples are circulated on a flow loop resembling circulation geometry where the pressure drop of the fluid is measured in linear sections and compared to the models. The experimental setup also serves as a small-scale well where different applications for this type of fluid could be tested. The objective of the project is to determine if the pressure drop generated by these samples when magnetized can be high enough to control a fluid loss, to create a strong sealing mechanism as an open-hole packer or other potential mechanisms.

▼ In the vicinity of the pseudocritical point, supercritical carbon dioxide (sCO₂) undergoes a steep change in properties from “liquid-like” to “gas-like” as it is heated at a constant pressure. At the same time, there is a large spike in specific heat which can yield high heat transfer coefficients and heat capacity rates. These unique properties have made sCO₂ an attractive working fluid in next generation power and HVAC&R technologies. Microchannel heat exchangers are being used to safely and efficiently utilize the high pressure fluid in these applications. However, prior investigation of heating of supercritical CO₂ has primarily focused on circular, uniformly heated channels at relatively low heat flux for nuclear power applications. Thus, it is unclear if models and correlations developed from large circular tube data can be scaled down to the smaller, non-circular channels, with non-uniform heating. In the present work, a methodology is developed to experimentally characterize heat transfer for multiple parallel microchannels with a hydraulic diameter of 0.75 mm and aspect ratio of 1. Experiments are conducted over a range of heat fluxes (20 ≤ q” ≤ 40 W cm⁻²), mass fluxes (500 ≤ G ≤ 1000 kg m⁻² s⁻¹), reduced pressure (1.03 ≤ P[subscript R] ≤ 1.1), and inlet temperatures (20 ≤ T[subscript in] ≤ 100°C) in a parallel square microchannel test article with a single-wall constant heat flux boundary condition. Local and average heat transfer coefficients are experimentally measured and the results are compared to previously developed correlations. The predictive capabilities for the supercritical models were poor, with the lowest mean absolute percent error (MAPE) of 55.3% for the range of bulk fluid temperatures, heat fluxes, and mass fluxes. Interestingly, subcritical correlations were also investigated and yielded much lower MAPE than 80% of the supercritical correlations even though the effects of variable fluid properties were not taken into account. The subcritical correlations did not incorporate property ratios to account for the variability in fluid properties; in some supercritical correlations it was found to add additional uncertainty for the case of the present study. The effects of buoyancy and flow acceleration were also evaluated. Based on dimensionless criteria, buoyancy was expected to play a role in heat transfer, especially when the bulk fluid temperature is below the pseudocritical temperature. However, the relative importance of flow acceleration was inconclusive. Despite the apparent importance of buoyancy effects, heat transfer was not degraded, as would be expected in larger, circular, uniformly heated tubes. The mixed convection could be inducing a density driven swirling with the stratification of low-density fluid near the top (unheated). This would ultimately improve the heat transfer at the bottom portion of the test section channels. Therefore, the flow geometry and the non-conventional heated boundary could be improving the heat transfer even with buoyancy driven… Advisors/Committee Members: Fronk, Brian M.

▼ A thermally actuated non-cantilever-beam micro-electro-mechanical viscosity sensor is presented. The proposed device is based on thermally induced vibrations of a silicon-based membrane and its damping due to the surrounding fluid. This vibration viscometer device utilizes thermal actuation through an in-situ resistive heater and piezoresistive sensing, both of which utilize CMOS compatible materials leading to an inexpensive and reliable system. Due to the nature of the actuation, thermal analysis was performed utilizing PN diodes embedded in the silicon membrane to monitor its temperature. This analysis determined the minimum heater voltage pulse amplitude and time in order to prevent heat loss to the oil under test that would lead to local viscosity changes. In order to study the natural vibration behavior of the complex multilayer membrane that is needed for the proposed sensor, a designed experiment was carried out. In this experiment, the effects of the material composition of the membrane and the size of the actuation heater were studied in detail with respect to their effects on the natural frequency of vibration. To confirm the validity of these measurements, Finite Element Analysis and white-light interferometry were utilized. Further characterization of the natural frequency of vibration of the membranes was carried out at elevated temperatures to explore the effects of temperature. Complex interactions take place among the different layers that compose the membrane structures. Finally, viscosity measurements were performed and compared to standard calibrated oils as well as to motor oils measured on a commercial cone-and-plate viscometer. The experimentally obtained data is compared to theoretical predictions and an empirically-derived model to predict viscosity from vibration measurements is proposed. Frequency correlation to viscosity was shown to be the best indicator for the range of viscosities tested with lower error (+/- 5%), than that of quality factor (+/- 20%). Further viscosity measurements were taken at elevated temperatures and over long periods of time to explore the device reliability and drift. Finally, further size reduction of the device was explored. Advisors/Committee Members: Fuller, Lynn.

▼ Process fluids may be degraded by large concentrations of suspended particles, formations of gel slugs, or the infiltration of air bubbles. The scattering of ultrasound is dependent upon the relation of the wavelength and the scatterers' dimensions. Relatively large objects are easily detected because of their strong scattering in the short wavelength limit (SWL), but small ones may be missed because of their weak scattering in the long wave length limit (LWL). When the object dimension is comparable with the wavelength of ultrasound (intermediate region), the approximations of both the SWL and the LWL do not apply. The work described in this thesis has experimentally investigated the scattering characteristics of particles in the intermediate region in order to estimate the size distribu tion of particles in some industrial fluids. A log normal particle size distribution which has a mean close to the ultrasound wavelength is selected and three kinds of industrial fluids are used in the experimentation. These lab-made fluids have various particle concentra tions so that the possible ranges of real conditions could be covered. A circulating fluid system is employed to simulate an industrial process. The ultrasonic images of particles in fluids are produced by an acoustic imager and are processed by an image processing sys tem. Different signal gains are used in the imager to test the effects of signal compensation on images. In ultrasonic video images, echoes of independent particles are recognized, adjoining or overlapping echoes are segmented by morphological operations, and each echo area of particle is individually measured. Also, particle size distributions are found and an exponential regression approach is proposed. The frame processing rate could be considered real-time processing because it is less than a second. The results demonstrate that moving scatterers detected by ultrasound can be recognized in real time by the system and their sizes can be individually determined as well as their statistical distribution in each trial period. Finally, rules have been found to estimate the original distribution of particles from derived system parameter and observed data. Advisors/Committee Members: Dougherty, E.

▼ The processes responsible for generating the mean azimuthal atmospheric winds observed on Jupiter and Saturn, which feature large prograde equatorial jets and jets of alternating direction at higher latitudes, have yet to be conclusively resolved. Results from three dimensional numerical models of thermal convection in a thin spherical shell have supported the theory that they are a surface manifestation of organized flow deep within the planets. While these models have been able to reproduce the general features of the observed zonal flow, computational limits restrict them to parameter regimes many orders of magnitude more modest than those thought to exist in the planets. A more efficient numerical model is required to study this phenomenon at more realistic parameter values, and would permit an investigation of the dependence of the solution on the parameters of the system and initial conditions, as well as the long time scale dynamics of zonal winds. The current thesis takes advantage of the rigid columnar flow structures that are produced by the rapid planetary rotation, as observed in the results of 3D simulations, to develop a two dimensional quasigeostrophic model of the system for a Boussinesq fluid. By averaging the equations of motion over Taylor columns in the axial direction, and simulating the mean variables in a 2D virtual equatorial plane, the essential dynamics can be modeled while collapsing the problem into one fewer dimension. To develop such a model, the standard quasigeostrophic framework, and existing numerical models based upon it, have been generalized to the geometry inside the tangent cylinder which circumscribes the inner spherical boundary of the convecting shell. Here, buoyancy in the axial direciition, which is not considered in the traditional QG framework, is responsible for forcing axial convection and the turbulence which leads to jet generation. Thus, in addition to the traditional QG equations, we must also solve the averaged axial flow equation to model this effect. Numerical simulations of our 2D QG model demonstrate that this approach can capture much of the dynamics of 3D convection. The system variables all have amplitudes which are the same order of magnitude as solutions from full three dimensional models. Additionally, alternating zonal jets similar to those observed on Jupiter can be produced.

▼ The scope of this research is to study the rheological behavior of an oil based mud (OBM) sample from the Mexican side of the Gulf of Mexico (GOM) under extreme conditions of High Pressure High Temperature (HPHT). In the coming years many HPHT wells are going to be drilled in this area of the GOM. Currently Mexican Oil and Gas industry is already open to international operators because the Mexican energy reform has been approved, so it is important to study the possible drilling fluids that will be used. These fluids can be within any of these 3 tiers of HPHT classification: HPHT, ultra (uHPHT) or extreme (xHPHT). The sample was submitted to extreme HPHT conditions, by using the state-of-the-art Model 7600 HPHT Viscometer that is capable of measuring drilling fluid properties up to 40,000 psi and 600 °F. During the laboratory tests performance, it was noticed that erroneous results were obtained by several mechanical failures. It should be noted that the spare parts take a long time to arrive-around 3 weeks. One of the failures was that the pivot of the spring assembly got inside the device, so the bob was spinning nonstop. For this reason the readings of the dial went well beyond the allowed range; another mechanical failure was that the spring of the spring assembly was loose, which did not allow us to obtain a correct reading of shear stress at high pressures and low temperatures; also the baffle does not separate the pressurizing oil from the sample, mixing these two fluids and obviously affecting the properties of the sample. This was noticed by running one test with baffle and another without it getting very similar results. The rheological behavior of the sample showed that the viscosity is inversely proportional to temperature and directly proportional to pressure, noticing a failure point at 300 °F, because of sample degradation. Moreover the rheogram’s curves obtained are quite similar to a second degree polynomial function, with R-squared values ranging from 0.95 to 0.99; hence an equation can be adjusted in the future by extrapolating different pressure and temperature values.

▼ Fluids confined in porous media play a significant role in many engineering applications. Modeling fluids in oil reservoirs, adsorption based separations, and heterogeneous catalysis requires the accurate prediction of thermodynamic properties at a wide range of conditions. For confined fluids, this task involves accounting for the fluid-solid interactions induced by proximity to a solid wall. Most engineering models are only able to predict average properties of the system and fail to give information related to the heterogeneity of the confined fluid. Such information could be obtained through more rigorous but computationally expensive methods. In this work, an approach of intermediate complexity is developed to determine equilibrium properties of confined fluids, and to obtain local distribution of properties in the system. In this model, the variation of properties throughout the system takes place across regions that are defined depending on the effects present. Regions where confinement effects are important are further discretized into layers to capture local distribution within the confinement. For all elements, the volume is specified together with the temperature, and the total amount of each component. Thus, minimizing the Helmholtz energy determines the number of moles in each element; subsequently other properties are obtained. The Helmholtz energy accounts for internal interactions through an equation of state (EoS), in this work the Peng Robinson EoS is used. Additionally, the Helmholtz energy function includes an external contribution represented by an adsorption potential to account for fluid-solid interactions The Steele 10-4-3 potential was used for the confinement of light hydrocarbons in activated carbon. The prediction of local behavior was found to be comparable to the classical Density Functional Theory (DFT) calculations. Moreover, the Dubinin-Radushkevich-Astakhov (DRA) potential was utilized to predict confinement of binary and ternary mixtures of methane, nitrogen, carbon dioxide on activated carbon, and the results were found to agree reasonably well with experimental data. Finally, the ability of the framework to model systems where confinement as well as other effects are present is demonstrated through predicting the molar distribution in a porous reservoir where gravitational effects are accounted for.

This is a 'sandwich thesis' consisting of four publications I contributed to during my M.Sc. work. These papers are the results of three types of experiments. Paper 1 studies the formation of non-uniform spin-cast polymer films. Spincoating is widely used to prepare thin polymer films of reproducible thickness. Typically spincoating produces highly uniform films, however in certain circumstances the process results in films with non-uniform surface topographies. The origin of such topographies is not fully understood and the formation of non-uniform films represents a practical problem in both research laboratories and industrial settings. In Paper 1 we find that the formation of non-uniform films is dependent on temperature. Furthermore, our results indicate that surface instabilities form as a result of the Marangoni effect. Finally, we demonstrate that non-uniformities in spin-cast films can be avoided simply by spincoating at lower temperatures. In Papers 2 and 3 we study the capillary driven levelling of polymer films with non-uniform surface geometries and compare our results to the theoretical predictions of the two-dimensional capillary-driven thin film equation. In Paper 2 we prepare polymer films with small surface perturbations and track their evolution above T_g as the surface flattens. We find that all perturbations approach a universal self-similar attractor at long times, as predicted by theory. Our results also show that the time taken for the perturbations to convergence to the attractor depends on the initial volume of the perturbation. In Paper 3 we prepare samples with a rectangular trench geometry and follow their evolution above T_g as surface forces cause the trench to fill in. At long times we observe a change in the levelling dynamics that is associated with a change in the boundary conditions governing the flow. In Paper 4 we use crazing experiments to probe two types of non-equilibrium entanglement networks. First, we study spincast polymer films and find that chains are stretched compared to equilibrium Gaussian chains. Furthermore, we find that the entanglement network relaxes on timescale on the order of one reptation time. Next, we stack two films in the glassy state to create a bilayer. Chains on either side of the mid-plane of the bilayer suffer a loss of entropy because of their restricted conformations. In the melt, the interface heals. We find it takes less than one reptation time for the bilayer film to become indistinguishable from a single film.

This thesis consists of two related studies presented as three separate manuscripts (all three have been published in peer-reviewed journals) and a study protocol that has been submitted for peer-reviewed funding. The over-arching theme of this thesis was to better characterize the efficacy of different intravenous fluids used for the resuscitation of intensive care unit (ICU) patients with severe sepsis or septic shock. We performed an extensive search including multiple databases which found 20 randomized controlled trials (RCTs) that examined the effects of different intravenous fluids used in septic patients and met our a priori inclusion and exclusion criteria. In the first manuscript, we described in detail the composition of the 19 unique fluid products that were used in the various studies. This description included the fluid type, trade name, osmolality, tonicity, electrolyte content, molecular composition, pH, and manufacturer. We reviewed manufacturer’s websites, product monographs, and emailed industry representatives or study authors for more information regarding the fluids as required. The results of this study and systematic review led us to the second and third manuscripts which reported on a Bayesian network meta-analysis (NMA) of all fluid type comparisons. Despite multiple well-done RCTs, comparative data regarding the clinical effect of different resuscitative fluids when used for sepsis was incomplete. Most RCTs used 0.9% saline (normal saline) as control fluid and very few studies compared colloids directly. The advantage of using an NMA model in this setting was the ability to include indirect data into the overall point estimates. Data was abstracted from the 14 studies which focused on adult ICU patients and analyzed examining the outcomes of mortality (manuscript2) and the use of renal replacement therapy (RRT) (manuscript #3). Certainty of evidence was evaluated for both outcomes using the GRADE approach. Results of the analysis clearly document the harm of starch-based fluids when used in septic patients. Albumin containing fluids and crystalloids (such as normal saline and Ringer’s Lactate) are better options. Lower chloride solutions, such as Ringer’s Lactate, showed a signal towards decreased mortality and a decreased use of renal replacement therapy when compared to higher chloride fluids, such as normal saline, however this was based on indirect data, not statistically significant, and warrants direct comparison trials. The final component of this thesis is a pilot study protocol for a study assessing the feasibility of a larger RCT examining the effect of low chloride versus high chloride fluids for resuscitation in patients with sepsis and septic shock. This protocol has been submitted as part of a peer-reviewed grant with the hopes of addressing this clinically important and timely question.

Purpose: Septic shock continues to be a leading causes of pediatric mortality worldwide. Currently there is only limited literature detailing what constellation of signs and symptoms may predict children with septic shock. In particular, there is scant literature on whether excessive fluid resuscitation (> 60 mL/kg) following a diagnosis of hypotension or if delays in vasopressor initiation following fluid-refractory septic shock lead to worse outcomes. I hypothesize that in children in the ED with septic shock, greater amounts of fluids and the time to vasopressor initiation after last fluid bolus is associated with worse outcomes. Methods: This project is part of a larger retrospective, time series study describing baseline data for quality of care metrics in the diagnosis and management of pediatric septic shock. Children 0-18 years of age were eligible for the study if they presented to the ED from November 2012 to December 2014 with signs and symptoms concerning for sepsis and had hypotension for age during their ED course. Predictors of outcomes were total volume of fluid in milliliters per kilogram received in the ED following hypotension and time to vasopressor initiation following determination of time of fluid-refractory shock. Outcomes of mortality, total hospital length of stay, intensive care length of stay, and duration of vasopressors were assessed. Outcomes were controlled for potential confounders of age and severity of illness using the Pediatric Risk of Mortality score III. Results: 408 patients underwent analysis. 220 (53.9%) were males (95% Confidence Interval: 49.0%-58.7%). Fluid administration of more than 60 mL/kg in the ED was not associated with worsened mortality, intensive care or hospital length of stay, or longer vasopressor requirement. After controlling for severity of illness and age, the intensive care length of stay and duration of vasopressor support was statistically longer (p value = .045 and 0.008, respectively). Specifically, for every minute of vasopressor delay, intensive care length of stay and duration of time spent on vasopressor support increased by 19 and 13 minutes, respectively (p<.05). Conclusions: Delays in vasopressor initiation from fluid refractory shock is associated with an increased intensive care length of stay and longer time on vasopressors. These results call for the exploration of interventions that can improve timeliness of vasopressor initiation.

▼ This thesis reports the use of Rheo-NMR, that is, a class of techniques within the realm of magnetic resonance which are both confirmatory and complementary to rheometric experiments on materials which can best be classified as complex fluids. The physical properties of such fluids are both hybrid and, in general, vaguely defined. In displaying characteristics attributable to both ideal fluids and elastic solids, the term `complex fluid', in a very real sense, epitomises all the fluids with which every human deals with (and is comprised of) daily. With a multitude of potential candidates for further research then, here we confine ourselves to fluids of molecules and aggregates which are either linear polymers or at least maintain the curvilinear one-dimensional topology of linear polymers. Magnetic resonance is an ideal research tool in this regard, as it is in many respects a rather statistical and insensitive tool from a signal-to-samplevolume perspective, precisely the regime in which the dynamics of a macroscopic collection of macromolecules is relevant. Material deformation is the mechanism upon which rheological measurement depends, and the first research presented here reports on a numerical simulation of the NMR signal of sheared polymer melts. Proton NMR relaxation times of such melts have previously been measured experimentally and found to depend on the shear rate applied by a horizontal Couette geometry, presumably due to the alignment of the mean-field boundaries of the space in which the polymer may reside, known as the polymer tube. The restrictions forming the tube are the other polymers in the bulk, around which an exemplar polymer molecule must meander. In diffusing through this tube, whose direction between entanglements is random in equilibrium, at any time, the return-to-origin correlation for a single spin returning to its locally anisotropic environment generates the least NMR transverse relaxation, as the sum contribution from all tube segments is random. When a deformation-related transformation matrix is applied to the coordinates of entanglements in the polymer, tube segments are no longer isotropically distributed, and an enhanced relaxation process results. Here we present the results of a numerical simulation of this procedure, based on the earlier model of Ball, Callaghan and Samulski, in addition to measurements of the transverse NMR relaxation by Cormier. Not only does it demonstrate qualitative agreement, the NMR signal can be simulated quantitavely or conversely, the size of several key polymer physics parameters can be found through fitting to the NMR signal. Proton NMR spectroscopy is inherently simpler than deuteron NMR spectroscopy, in which the nucleus of interest is quadrupolar. However, a large section of this thesis deals with the structures and response of worm-like micellar structures in solution, for which alignment data cannot reasonably be measured with the proton alone. The most used sample in this thesis is that of the BASF nonionic block copolymer Pluronic P105… Advisors/Committee Members: Callaghan, Paul.

▼ Previous studies in Magnetically Stabilized Fluidized Bed (MSFB) are well known for conventional two-phase, gas-solid or liquid-solid fluidization. Many researchers have investigated the fluid dynamic behavior of the MSFB, however, all of these studies are based on a uniform magnetic field that is constant throughout the bed column. Currently, there are no references in the open literature indicating either fundamental or applied research with a magnetically fluidized bed where a non-uniform magnetic field is used in a two-phase liquid-solid fluidization. In this study, the fluid dynamic behavior of a Magnetically Assisted Fluidized Bed (MAFB) in a non-uniform magnetic field is experimentally observed. In the MAFB, a magnetic force, F[sub m] , is created which acts on the ferromagnetic particles (20% ferrite) by varying the magnetic field intensity from the top to the bottom of the fluidization column. However, the field gradient is kept constant throughout the bed. Because of the differences in the magnetic field intensity at any location in the bed, the particle holdup, or inversely the bed voidage, has to change to accommodate the equilibrium of forces acting on the particles (drag force, gravitational force, buoyancy force, and magnetic force). In the laboratory experiments, performed magnetic field gradient, [see PDf for equation] Alm/m, -18,289 Alm/m, -20,543 Alm/m and -33,798 A/m/m) and fluid flow rate (U[sub 0] =0.0153 m/s, 0.0176 m/s, 0.0199 m/s and 0.0222 m/s) are varied. These experiments show that the increase in the magnetic field gradient and the magnetic field intensity results in the decrease in the height of the bed, and therefore, in the decrease of the bed voidage. The dynamic pressure drop, [delta]P[sub f][sub(d)], is also experimentally measured, then converted to a corresponding voidage. The relationship between the dynamic pressure drop and the bed voidage is given by the following equation:[see PDF for equation] The fluid dynamic behavior of the MAFB is described by the equation of motion and the equation of continuity for both liquid and solid phases. A mathematical model is developed and used to evaluate the voidage distribution in the MAFB. The resulting expression for the voidage distribution in the MAFB is given as [see PDF for equation]. Experimentally obtained bed voidage data in both, laboratory experiments (1g) and on board of the NASA KC-135 plane (0g) fit very well the above equation which does not have any adjustable parameter.
