▼ This study investigates the hydrodynamic characteristics of droplet impinging on heated surfaces using High Speed High Resolution (HSHR) imaging and evaluates the effect of surface temperature and using water and a nanofluid on a polished and a nano-structured surface. Three types of surfaces are used in the study: polished silicon, nano-structured porous silicon and gold coated polished silicon. Seven different surface temperatures including single phase (non-boiling) and two phase (boiling) conditions are studied. Droplet impact velocity, transient spreading diameter and dynamic contact angle are determined using image processing. Five stages are observed during impingement: initial impact, boiling (if the surface temperature is high enough), near constant wetting diameter evaporation, fast receding contact line evaporation and final dry-out. Results of water and a water based single-wall-carbon-nano-tube (SWCNT) nanofluid impinging on a polished silicon surface are compared to determine effects of nano-particles on impinging dynamics. The data show that the nanofluid exhibits larger spreading velocities, larger spreading diameters and an increase in early stage dynamic contact angle. The results of water impinging on both polished silicon and nano-structured silicon disks are compared to determine effects of the nano-structured surface on impingement dynamics. It is found that the nano-structured surface enhances the heat transfer for evaporative cooling at lower surface temperatures which is indicated by a shorter evaporation time. Ultimately, using nanofluid and nano-structured surface can reduce the total evaporation time up to 37% and 20%, respectively. Experimental data are compared with models that predict dynamic contact angle and non-dimensional maximum spreading diameter. Results show that the molecular-kinetic theory's dynamic contact angle model (M-K model) agrees well with current experimental data at low velocities range corresponding to later times during impingement, but over-predict at high velocities range corresponding to early times of initial impact. Predictions of maximum spreading diameter based on surface energy analysis are compared with current experimental data. Results indicate that all the four models over-predict unless empirical coefficients are adjusted to fit the test conditions.

▼ An experimental investigation was carried out to study the effect of heater surface preparation on pool boiling of nanofluids. The boiling surface was prepared using different methods: (1) using a diamond turning machine, (2) a conventional lathe machine, and (3) polished using emery sandpaper. The average surface roughness of the diamond turning machined surface was 6 nm and 470 nm for the surfaces prepared using the lathe and sandpaper. The boiling surfaces considered in this study are flat copper surfaces with a diameter of 25.4 mm. Al2O3-Water nanofluids prepared using nanoparticles with an initial size of 10 nm and concentration of 0.05%wt were used throughout the present study. In order to improve the nanofluids stability Sodium dodecylbenzenesulfonate (SDBS) was added to the base fluid (water) with a concentration of 0.1%wt. In order to understand the effect of the nanofluids and the surfactant separately and together, pool boiling experiments using distilled water only, nanofluids, distilled water plus the SDBS surfactant, and nanofluids mixed with SDBS (nanosuspensions) were carried out on clean surfaces. The nanofluids and nanosuspensions boiling experiments were followed by distilled water boiling experiments in order to assess the change of the surface characteristics due to any nanoparticles deposition. The same set of boiling experiments was carried out on each of the three prepared surfaces. The experimental results indicated that for the smooth and rough machined surfaces, the heat transfer coefficient was increased for the nanofluids and the nanosuspensions with respect to distilled water. Distilled water boiling experiments on the unclean (used) surfaces showed that the heat transfer behavior is almost similar to the distilled water on the clean surface, which indicates that the deposition on the smooth and rough machined surfaces was minimal and hence the enhancement in the heat transfer was due to the change in the thermo-physical properties of the nanofluids and not due to the change in the heater surface condition. A similar trend was observed in the case of the polished surface in which case nanofluids and nanosuspensions resulted in an enhancement in the rate of heat transfer. However, distilled water boiled on unclean surfaces showed that the boiling curve has shifted to the left compared with the curve of the distilled water on the clean surface. Boiling of distilled water on unclean surfaces showed that the boiling curve was enhanced, which can be attributed to the change in the surface condition and the change in the thermo-physical properties of nanofluids. Photographs of the boiling surfaces and surface measurements taken before and after the nanofluids and nanosuspensions experiments showed that the machined surfaces had less nanoparticles deposition than the sandpaper polished surface. These results indicate that the method of surface preparation has a significant effect on nanoparticles deposition and consequently on the pool boiling heat transfer… Advisors/Committee Members: Hamed, M.

Cooling is indispensable for maintaining the desired performance and reliability of a wide variety of products, such as computers, car engines and high-powered laser. With the increase of heat loads and heat fluxes caused by more power and smaller sizes for these products, cooling is one of the top technical challenges faced by the industries like microelectronics, transportation, manufacturing, metrology and defense. Recently, single-phase liquid cooling techniques such as microchannel heat sink and two-phase liquid cooling technologies like heat pipes, thermosyphons, direct immersion cooling and spray cooling for chip or package level cooling have emerged. However, with continued miniaturization, increasing heat dissipation and inherently low thermal conductivity is a primary limitation in developing energy-efficient heat transfer fluids that are required for ultrahigh-performance cooling in new generations of products. Therefore, the cooling issue will intensify in many industries from electronics and photonics to transportation, energy supply, defense and medical. Development of the nanomaterials technology has made it possible to structure a new type of heat transfer fluids formed by suspending nanoparticles (diameter less than 100nm) in conventional base fluids like water and ethylene glycol. Choi (1995) coined the term Nanofluids to refer to this new class of fluids that exhibits thermal properties superior to those of their base fluids. The nanoparticles suspended in a base liquid are in random motion under the influence of several acting forces, such as Langevin force which is a random function of time, and reflects the atomic structure of the medium. The exact role of this stochastic motion on the morphology of nanofluids and energy transport inside the nanofluids is not well understood. Due to rapid fluid mixing effects strengthens the energy transport inside the nanofluids by modifying the temperature profiles.

▼ Nanofluids are two-phase mixtures of base fluids and nanoparticles. They possess unique thermal, magnetic, electronic, optical and wetting properties, and thus have tremendous applications in many fields. For practical applications of nanofluids in heat-transfer systems, we often try to achieve a global aim such as optimization of system highest temperature and optimization of system overall thermal resistance. To improve energy efficiency, attention should focus on designing nanofluids for the best global performance. As indicated by constructal theory, flow structures emerge from the evolutionary tendency to generate faster flow access in time and easier flow access in configurations that are free to morph. Constructal theory can not only predict natural flow architectures but also guide design of flow systems. In this thesis, constructal design is applied to study nanofluid heat conduction such that the system (global) performance can be constantly improved. An examination of the variation of preferred heat-transfer modes for different matter states concludes that the preferred heat-transfer modes for solid, liquid and gas are conduction, convection and radiation, respectively. After an analogy analysis of plasma heat conduction and nanofluid heat conduction, it is proposed that forming continuous particle structures inside base fluids may enhance the heat conduction in nanofluids. Staring from the conventional nanofluids with particles dispersed in base fluids (dispersed configuration of nanofluids), we first perform a constructal design of particle volume fraction distribution of four types of nanofluids used for heat conduction in eight systems. The constructal volume fraction distributions are obtained to minimize system overall temperature differences and overall thermal resistances. The constructal overall thermal resistance is found to be an overall property fixed only by the system global geometry and the average thermal conductivity of nanofluids. The constructal nanofluids that maximize the system performance under dispersed configuration are the ones with higher particle volume fraction in region of higher heat flux density. Based on the proposal of forming continuous particle structures inside base fluids, blade configurations of nanofluids are analyzed analytically and numerically for both heat-transferring systems and heat-insulating systems. Comparisons are made with dispersed configurations of nanofluids with constructal particle volume fraction distributions or thermal conductivities of upper or lower bounds. The superiority of blade configuration is always very obvious even with rather simple particle structures. As the blade structures are more sophisticatedly designed, system performance of blade configuration will become even better. To improve the particle structure design, efforts are put on optimizing crosssectional shape of particle blade to achieve better system performance. The triangular-prism-shaped blade is shown to perform the best. Since heat conduction and fluid flow inside trees… Advisors/Committee Members: Wang, L.

▼ Fluid flows at micro- and nanoscale are essential in integrated fluidic devices and micro total analysis systems such as Micro-/Nano-Electro-Mechanical Systems (MEMS/NEMS), which have tremendous applications in biology, medicine, chemistry and engineering. Nanoscale flows could be very different from macroscopic flows due to the high surface-area-to-volume ratio and complex molecular interactions. To promote the applications of nanoscale flows, extensive work is required to study the flows in nanoconfinements. The objectives of this thesis are to investigate the flow fashions and explore the applications of nanochannel flows through experiments. First, the Poiseuille flows in nanochannels are examined. Experimental results show that the flow rate undergoes a transition between two linear regimes as the shear rate is varied. The transition indicates that the nonslip boundary condition is valid at low shear rate. When the shear rate is larger than a critical value, slip takes place and the slip length increases linearly with increasing shear rate before approaching a constant value. Second, a nanofluidic diode for simple fluids without moving part is proposed and investigated by using heterogeneous nanochannels, half of which is hydrophilic and the other half is hydrophobic. The device accepts water flows in the direction from hydrophilic to hydrophobic, while the flows in the other direction are blocked for pressure drop range between 0 and 0.63 MPa. As the upstream pressure becomes higher than 0.63 MPa, the fluidic diode turns to be a rectifier, which allows flows in both directions but with different flow rates. At sufficient high driving pressure, the fluidic system fails in flow rectification, analogous to the breakdown of electro diodes. Finally, a waste heat driven self-adaptive cooling system based on heterogeneous nanochannels is fabricated and studied. It is found that continuous coolant flux from the hydrophilic side to the hydrophobic side can be generated under symmetric temperature gradients. Linear dependence of volumetric flux on the temperature gradient is observed. The mechanism of flow behaviors is evaluated through the coupling effects of temperature gradient and fluid-surface interaction.

▼ Droplet evaporation is a common and natural phenomenon under an unsaturated vapor pressure. This process appears in many applications such as spray cooling, inkjet printing and fuel combustion. Nanofluids are advanced fluids with thermophysical properties that are different from their base fluids. The thermophysical properties include thermal conductivity, viscosity and enthalpy of vaporization etc. Owing to the change of thermophysical properties, nanofluids are used in many applications such as heat transfer, automobiles and electronics. The evaporation kinetics directly influences the performance of the applications and the nanoparticle size affects the thermophysical properties and hence it changes the evaporation kinetics of the nanofluid. Researchers are interested to investigate how the particle size influences the evaporation kinetics of nanofluids of different concentrations. After evaporation, a residue pattern is left on a substrate which relates to the evaporation kinetics, particle size and concentration. Therefore, this study is about the evaporation kinetics and residue pattern of different particle sizes and concentrations. 9 nm, 13 nm, 20 nm, 80 nm and 135 nm diameters of Al2O3 particles suspended in water were investigated, experimentally, in relation to the evaporation kinetics. The sessile droplet was deposited on a stainless steel substrate. It was found that the evaporation kinetics of any concentrations of 9 nm and 13 nm, where are 0.14 and 0.18 respectively, are higher than those of 20 nm, 80 nm and 135 nm, where are around 0.12 to 0.13. The evaporation kinetics affects the residue pattern. From the results, the patterns can be classified into two types: (1) ring-shaped and (2) uniform. It is noted that concentrations below 1 vol% of 9 nm and 13 nm result in ring-shaped residue patterns while the patterns of concentrations above 1 vol% of 9 nm and 13 nm and any concentrations of 20 nm, 80 nm and 135 nm are uniform. The different pattern is because of the various internal flows of different particle size.

▼ DNA is the central storage molecule of genetic information in humans and almost all other organisms. Analyzing the genetic information along the DNA molecule is of great importance in life science and biomedical engineering. Recently, nanofluidics has been recognized as an efficient approach to study the behavior of DNA at the single-molecular level, which can unravel the phenomena that remain hidden in conventional bulk experiments. When confined in nanochannels, the coiled DNA molecules naturally stretch out as a combined result of the elastic properties and the excluded volume effects. Therefore, a reliable nanofluidic platform is the prerequisite for single-molecule DNA studies. This thesis focuses on the development of sub-100 nm disposable nanofluidic devices and the experimental demonstration of such devices for biomolecular detection and analysis. We first investigated various techniques for fabricating low-cost nanochannels on different substrates. We showed that the lithography-free nanocracking on a polystyrene substrate is a promising approach for lab-on-chip nano-manufacturing. Based on such nanocracking technology, an on-demand nanofluidic pre-concentrator was developed, which leveraged isolated droplets to avoid the sample diffusion and dispersion issues as compared to conventional devices. To prevent concentration decay during the sample ejection, a pressure-assisted strategy was introduced in the system for precisely positioning the concentrated sample plug at the ejecting nozzle. By integrating the ion concentration polarization with on-demand droplet generation, our system can adaptively encapsulate the highly concentrated sample and effectively enhance the long-term stability. We experimentally demonstrated the pre-concentration of a fluorescently labelled biomolecule, bovine serum albumin (BSA), by an amplification factor of 10,000. By adjusting the applied voltage, accumulation time, and pulsed pressure imposed on the control microchannel, our system can generate a droplet of desired volume with a target sample concentration at a prescribed time. Second, we developed a novel nanofluidic device to confine and align single-molecule DNA in dynamically formed nanochannels for optical analysis. By judiciously harnessing the microvalve control and the deformation of nanoslits made in the PDMS, we dynamically generated submillimeter-long uniform nanochannels with an effective confining dimension down to 20 nm based on low-cost soft lithography. Using such devices, we investigated DNA stretching and attained 80% of the contour length for DNA elongation. The curved edge of the microvalve smoothly bridges the different depths between the stretching nanochannels and the adjoining microchannels by more than 3 orders of magnitude, which greatly facilitates the introduction of DNA into the nanochannels without the need for high pressure or electric fields. Unlike traditional direct-bonded nanochannels, the sample nanochannels in our device recover in microscale when the pressure is released, eliminating…

▼ In this thesis, several critical topics related to PCR-based micro/nano-fluidic chip were studied: from the chip integration and fabrication (three PCR chips and one DNA detection chip were introduced), PCR optimization to materials’ PCR inhibition. A highly integrated PCR microfluidic chip combined giant electrorheological (GER) fluid actuated micromixer and micropump and a microheater array was demonstrated in chapter 2. Afterward a microheater and a thermal sensor were fabricated inside elastomeric PDMS micro channels by injecting silver paint (or other conductive materials) into the channels. With a high-precision control scheme, microheaters can be used for rapid heating, with precise temperature control and uniform thermal distribution. Using such a microheater and feedback system, the PCR experiment was carried out whereas the DNA was successfully amplified in 25 cycles, with 1 minute per cycle. As reported in chapter 4, we formulated a simplified PCR profile consisting of only two temperatures instead of the conventional three and found suitable PCR component concentrations for successful detection of genetic variation under optimized PCR conditions by utilizing raw saliva. We also tested the PCR-compatibility of 23 kinds of common materials in microfluidics with a simple and newly developed method. Our results provide an overview of which the materials are most PCR-friendly for microfluidic device fabrication. Based on the previous experimental results, a device consisting of an interchangeable PCR chamber, a temperature control component as well as an optical detection system was constructed. The DNA amplification happens on an interchangeable chip with the volumes as low as 1.25 μl and the total time of only 25 minutes to complete the 35 cycle PCR amplification. Within the PCR chip, the amplification of male-specific SRY gene marker by utilizing raw saliva was successfully achieved and the genetic identification was in-situ detected right after PCR by the optical detection system. Finally, initial experiments of DNA detection in nanoslot were reported. We have captured the impedance shift of the nanoslot for DNA is present in solution.

▼ Droplet microfluidics is a rapid developing research area, which has great promising application in lab-on-a-chip, point-of-care diagnostic and et al. In this thesis, micro/nano particles are introduced into droplet microfluidic chips for droplet generation, manipulation and application. They could be categorized in three types: magnetic nano particles(Fe3O4, Ni carbonyl iron), conductive micro/nano particles (Ag micro platelets and Carbon Black) and dielectric particles (giant electrorheological nano particles). Mono-dispersed magnetic micro spheres are prepared and their deformation under magnetic field is calibrated. Magnetically responded membrane is fabricated from magnetic elastomer CI-PDMS. Optimized ratio of CI/PDMS is found to be 2, and high efficiency micromixer is achieved by integrated the magnetic membrane into PDMS microfluidic chip. Then, structured AgPDMS pattern is integrated in microfluidic droplet detection chip as parallel electrodes and on-chip conducting wires. Connected with external detection circuit and Labview software, droplets could be detected and sorting according to their capacitance difference. Furthermore, GER fluids are injected into microfluidic channels, with the help of conducting component, 'smart' droplet generation and manipulation, as well as a universal droplet logic gate microfluidic chip is achieved, which shows the possibility of droplet communication and automatically control. Droplets could be coded, guided and stored, different logic functions could be conducted in one chip while varying the combination of applied voltages. What‘s more, droplet microfludic is also used in cell encapsulation for single cell manipulation (e.g. electroporation) to demonstrated application of droplet microfluidics. Some improvement in PDMS chip fabrication is presented for simplifying the fabrication of integrated multi-function microfluidic chips. All of these researches reveal the advantages of adoption of mircro/nano particles into droplet microfluidics: more control methods, more functionality and more automatically.

▼ Nanofluids are homogeneous mixture of dispersed solid particles in base fluids. These solid particles are usually smaller than 100nm. Suspended nanoparticles modify the properties of based fluids. It is claimed, in some literature, for nanofluids to have greater than expected heat transfer performance. Due to this, nanofluids have gained great attention from both research and development and industries active in cooling systems. This thesis reports several measurements of convective heat transfer coefficient in a horizontal open micro-tube test section under laminar flow regime. The test section has an inner diameter of 0.5mm made of stainless steel and it has a length of 30cm. Two different test sections have been built. The first one has 13 thermocouples attached on the wall and the second one has 10. These thermocouples are used to measure the wall temperature distribution along the tube. In addition, two more thermocouples are used inside the micro-tube, at the inlet and outlet, to measure the bulk temperature of the nanofluids. A syringe pump is used for injecting the nanofluids through the micro-tube. A DC power supply provides constant heat flux along the test section and a differential pressure transducer measures the pressure drop of the test section. Aqueous based Al2O3 (9 wt %), ZrO2 (9 wt %), TiO2(9 wt %), CeO2 (9wt %), CNT (0.15 wt %), and diamond (1 wt %) have been tested in this thesis. Local Shah’s correlation predicts very well the behaviour of these nanofluids. The results are compared with water in six different ways: heat transfer forconstant Reynolds numbers, volume and mass flow rates, pressure drops andpumping powers. Enhancement in heat transfer is recognisable only in thegraphs of Nu numbers for constant Reynolds numbers. This can be attributed to the higher viscosity for nanofluids. Moreover, friction factor for constant Reynolds numbers has been compared. All the nanofluids with the exception of Al2O3 and diamond suit quite well with Darcy-Weisbach correlation.

▼ The study of Nanofluids is an emerging field of research in the past decade. Nanofluid is a mixture of liquid and solid phase nanosized particles which have shown high thermal properties compared to the base fluid. Many researches have shown that nanofluids have improved thermal properties such as thermal conductivity compared with the base fluid, and these findings have led many researchers to look for the potential of applying Nanofluids in existing thermal systems. With microgrooves being a good method to increase the surface area for heat transfer, nanofluids and microgrooves may be used together to improve the performance of a cooling system. This thesis aims to study the stability of nanofluids and the effect of a microgrooved surface on evaporation of nanofluids. The most common way to prepare nanofluid is by two-step method which disperses dry nanoparticles in a base fluid. However, ultrasonication is needed to break down large clusters in order to produce a stable nanofluid. Experiments have been conducted to investigate the effect of ultrasonic time on the stability of nanofluids. An optimal duration of 1 hour ultrasonication has been identified and the pH value of a nanofluid without a surfactant can remain at a stable level for 5 hours. Microgroove is an opened channel with a dimension in micrometers. Liquid will be drawn into microgroove due to the presence of capillary pressure when immersed in liquid. The extended meniscus formed in a microgroove offers an increased surface area for evaporation. Experiment has been conducted to investigate the effect of a microgrooved surface on the evaporation rate of water and nanofluids under different environmental conditions. Results show that a microgrooved evaporator using water as the coolant offers an enhancement in the evaporation rate as large as 21.4% compared with the evaporator without microgrooves. By using 0.5 vol% Al₂O₃ nanofluid as a coolant, a further 44.6% improvement has been found. Microgroove evaporator and nanofluid could be used in different cooling system such as cooling tower.

▼ The analysis of nucleic acids and proteins is of great significance in genomics, proteomics, and clinical diagnostics. The past decades have witnessed the booming development of nanofluidic devices, which have outperformed traditional diagnostic and analysis techniques in terms of accuracy, sensitivity, efficiency, and sample consumption. Nanofluidic channels (capillaries) featuring critical dimensions comparable to those of biomolecules provide alternative routes to the manipulation and detection of such species, in an attempt to develop the micro total analysis system (μ-TAS). This thesis describes the development of monolithically integrated, robust, and cost-effective glass nanocapillaries and nanopores that can be utilized for the separation and detection of biomolecules. First, the integrated glass nanocapillaries featuring distinct cross-sectional profiles are demonstrated for different chromatographic modes, including normal phase, ion-valance, reverse phase, and hydrodynamic liquid chromatograph. The minimum plate heights achieved are typically below 2 μm and the theoretical plate numbers are in the order of 10⁵ plates/m for most chromatography modes investigated in the pressure range up to 100 psi. Second, an on-chip hydrodynamic chromatography of DNA fragments is demonstrated, based on centimeters-long glass nanocapillaries that are essential for resolving DNA in this chromatography mode. The microchip can rapidly separate a digest of Lambda-phage DNA in free solution (< 5 min under the elution pressure of 60 psi to 120 psi) and the number of theoretical plates exceeds 10⁵ plates per meter for 3.5- and 21-kbp-long DNA fragments. Third, continuous-flow electrophoresis of macromolecules is presented using an integrated capillary-well sieve arranged into a two-dimensional anisotropic array on silicon. The periodic array features thousands of entropic barriers, each resulting from an abrupt interface between a 2-μm-deep well (channel) and a 70-nm capillary. The baseline separation is achieved in less than 1 min within a horizontal migration length of ~1.5 mm. Last, a monolithically integrated nanofluidic diode biosensor featuring a highly regular pore diameter of ~50 nm is demonstrated for multiplexed detection of low-abundance specific biomarkers presented in both electrolyte buffer and human serum. The nanopore diode exhibits a comparable rectification behavior to that of a nanoslit but it can achieve an order of magnitude lower detection limit for cardiac troponin T (~ 1 fg/mL). This nanopore biosensor can multiplex detect various biomarkers, including Alpha-fetoprotein, Carcinoembryonic Antigen, and Human Epidermal growth factor Receptor 2 within human serum and therefore provide accurate information for the early diagnosis of cancer. Further applications of such nanopore arrays are also proposed, including a fast and high-throughput DNA sequence, and novel power generators relying on the osmotic pressure gradient.

Research Doctorate - Doctor of Philosophy (PhD)

This study investigated the heat transfer behaviour of nanofluids with focus on a magnetite nanofluid as an alternative for the next generation of cooling applications. The very first aim of this study was to shed light on conflicting data reported in the literature about the thermal conductivity of conventional nanofluids (non-magnetic). For this purpose, the thermal conductivity of different nanofluid samples were measured under different conditions (namely particle volume fractions, temperature and pH) and results were compared with theoretical prediction of mixture theory. Shortcomings of different hypotheses were examined, analysed and explained. All of the experimental data were within the ±10% boundary of theoretical mixture theory (i.e. Maxwell model). It was shown that higher thermal conductivity in the conventional nanofluids can be achieved by controlling the aggregation size (i.e. pH value). To test this hypothesis, artificial aggregates were generated by applying an external magnetic field to the magnetite nanofluid. Thermal conductivity enhancement by up to 160% was observed for 0.86 vol% magnetite nanofluids (Fe3O4-water), subjected to the magnetic field intensity of 32 mT parallel to the temperature gradient. On the other hand, the thermal conductivity of magnetite nanofluid is almost constant under the applied magnetic field perpendicular to the temperature gradient. Convective heat transfer coefficient of magnetite nanofluid under laminar flow condition was also considered in the absence and presence of an external magnetic field. Heat transfer in magnetite nanofluids with and without magnetic field has been performed previously. However, the extent of the experiments and analysis is the main goal which has been achieved through this study. It has been shown that the experimental data in the absence of an external magnetic field follows the prediction of standard correlation for laminar flow heat transfer (Shah equation) using the thermophysical properties of nanofluid. Up to 300% enhancement in convective heat transfer enhancement has been observed at Re=745 and the magnetic field gradient of 32.5 mT/mm. Moreover, the effect of magnetic field on pressure drop was insignificant. It is concluded here that aggregation is the main mechanism of heat transfer in nanofluids. The thermal conductivity and convective heat transfer coefficient of magnetite nanofluids can be altered far beyond the prediction of traditional theories by applying an external magnetic field.

▼ Nanofluids consist of nanometer-sized particles or fibers in colloidal suspension within a host fluid. They have been studied extensively since their creation due to their often times anomalous and unique thermal transport characteristics. They have also proven to be quite valuable in terms of the scientific knowledge gained from their study and their nearly unlimited industrial and commercial applications. This research has expanded the science of nanofluids into a previously unexplored field, that of cryogenic nanofluids. Cryogenic nanofluids are similar to traditional nanofluids in that they utilize nanometer-sized inclusion particles; however, they use cryogenic fluids as their host liquids. Cryogenic nanofluids are of great interest due to the fact that they combine the extreme temperatures inherent to cryogenics with the customizable thermal transport properties of nanofluids, thus creating the potential for next generation cryogenic fluids with enhanced thermophysical properties. This research demonstrates that by combining liquid oxygen (LOX) with Multi-Walled Carbon Nanotube (MWCNT) inclusion particles, effective thermal conductivity enhancements of greater than 30% are possible with nanoparticle volume fractions below 0.1%. Three distinct cryogenic nanofluids were created for the purposes of this research, each of which varied by inclusion particle type. The MWCNT's used in this research varied in a number of physical characteristics, the most obvious of which are length and diameter. Lengths vary from 0.5 to 90 microns and diameters from 8 to 40 nanometers. The effective thermal conductivity of the various cryogenic nanofluids created for this research were experimentally determined by a custom made Transient Hot Wire (THW) system, and compared to each other and to more traditional nanofluids as they vary by type and particle volume fraction. This work also details the extensive theoretical, experimental, and numerical aspects of this research, including a rather detailed literature review of many of the salient sciences involved in the study of cryogenic nanofluids. Finally, a selection of the leading theories, models, and predictive equations is presented along with a review of some of the potential future work in the newly budding field of cryogenic nanofluids.

▼ Experiments were performed to study forced convective heat transfer of de-ionized water (DI water) and aqueous nanofluids flowing in a microchannel. An array of temperature nanosensors, called ?Thin Film Thermocouples (TFT)?, was utilized for performing the experimental measurements. TFT arrays were designed (which included design of photomask layout), microfabricated, packaged and assembled for testing with the experimental apparatus. Heat removal rates from the heated surface to the different testing fluids were measured by varying the coolant flow rates, wall temperatures, nanoparticle material, nanoparticle morphology (shape and nanoparticle size) as well as mass concentrations of nanoparticles in the coolants. Anomalous thermal behavior was observed in the forced convective heat transfer experiments. Precipitation of the nanoparticles on the heat exchanging surface was monitored using Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray spectroscopy (EDX). Isolated precipitation of nanoparticles is expected to cause formation of ?nanofins? leading to enhancement of surface area and thus resulting in enhanced convective heat transfer to the nanofluid coolants. However, excessive precipitation (caused due to the agglomeration of the nanoparticles in the nanofluid coolant) causes scaling (fouling) of the heat exchanging surfaces and thus results in degradation of convective heat transfer. This study shows that the surface morphology plays a crucial role in determining the efficacy of convective heat transfer involving suspensions of nanoparticles in coolants (or nanofluids). Flow visualization and quantitative estimation of near-wall temperature profiles were performed using quantum dots and fluorescent dyes. This non-contact measurement technique for temperature and flow profiles in microchannels using quantum dots is expected to make pioneering contribution to the field of experimental flow visualization and to the study of micro/nano-scale heat transfer phenomena, particularly for forced convective heat transfer of various coolants, including nanofluids. Logical extensions of this study were explored and future directions were proposed. Preliminary experiments to demonstrate feasibility showed significant enhancement in the flow boiling heat flux values for nanofluids compared to that of pure solvent (DIW). Based on the novel phenomena observed in this study several other topics for future research were suggested, such as, using Surface Plasmon Resonance (SPR) platforms to monitor precipitation of nanoparticles on microchannel surfaces in real time (e.g., for generating surface isotherms).

▼ Liquid cooling technology is necessary to meet the ever-increasing thermal challenges in the field of microelectronics cooling. In liquid-cooling systems, flow through microchannel heat sinks provide high performance and compact cooling, but have a high pressure drop penalty. To address this issue, multi-layered/stacked microchannels have been proposed in the literature. Further, increase in cooling performance of multi-layered microchannels can be achieved using coolants such as nanofluids, having high thermal properties. In the present study, a finite-volume numerical code with SIMPLE algorithm was used to solve the flow and energy equations, to analyze the thermal performance of a two-layered microchannel with pure water as well as CuO-water nanofluid. Flow rates between from 50ml/min and 320ml/min were considered to study the effect of varyingow rate on the thermal performance. Also, different volume fractions of nanoparticles are considered to investigate their effect on the thermal performance. The results show that nanofluids enhance the thermal performance, but the increase is not substantial. Also, the effect of channel geometry on the thermal performance of the two-layered microchannel heat sink has been investigated at two constraints, namely, fixed flow rate and fixed pumping power. The results show that the channel height, channel width and fin width have a significant effect on the thermal performance according to the flow constraints applied. Based on the parametric study, an optimization is carried out to obtain minimal thermal resistance, taking into account realistic constraint of fixed pumping power. Optimal channel dimensions were found for a range of power values between 0.01W-0.8W, which is the current micropumping power range. The minimal thermal resistance is found to be, is 0:09K/W/cm2 with 4% CuO-water nanouid and at pumping power of 0.8W. The results demonstrate that nanouids do not appreciably enhance the thermal performance of two-layered microchannel heat sink. Advisors/Committee Members: Ghia, Urmila (Committee Chair).

▼ Nanofluidics is a fascinating field with great potentials for applications in science and engineering because of rich unveiled striking phenomena such as superfast flows in carbon nanotubes, fluid slip, and the Debye layer overlap. Those new discoveries benefit from the small size of nanoconfinements due to the high surface-area-to-volume ratio. However, the nanoscale confinement in turn raises considerable challenges. One is that a high infiltration pressure is usually needed to drive fluids into hydrophobic nanochannels. For carbon nanotubes, it has been shown that the infiltration pressure can be as high as 300 MPa. Such a high pressure poses challenges for the applications of nanofluidic systems. To find solutions to reduce the infiltration pressure, systematic investigations of water infiltration into hydrophobic nanochannels through molecular dynamics (MD) simulations are conducted. It is found that the classic Young-Laplace equation is invalid for nanochannels due to the entrance energy barrier. As the channel surface is tuned from superhydrophobic to hydrophobic, the infiltration pressure is greatly reduced by a factor of 7. Another challenge is to effectively regulate fluid flow in a specific direction with fixed structures at the nanoscale. Conventional microvalves can be used for flow control. However, they usually contain moving parts, which require external actuations to provide driving forces, cause reliability issues at the nanoscale, and damage other delicate molecules. Microscopic fluidic diodes without moving parts, analogous to that of electronic diodes, if they can be developed, would significantly advance micro/nanofluidic technologies. Inspired by the work on the infiltration pressure, three novel, passive nanofluidic diodes (no moving parts) for simple fluids using heterogeneous, nested, and non-uniform nanochannels are developed. It is shown that the fluidic diodes can achieve unidirectional water flows in a wide range of pressure drops. The pressure drop range for the fluidic diodes can be varied by modifying the surface wettability and channel structure. The fluidic diodes can be used for flow control in integrated micro- and nanofluidic devices and fluidic logic operations.

▼ This thesis contributes to the investigation of controls of nanofluidic fluids by utilizing hybrid surface patterns in nanochannel. Nanofluidics is a core and interdisciplinary research field which manipulates, controls and analyzes fluids in nanoscale and develop potential bio/chemical applications. This thesis studies the surface-induced phenomena in nanofluidics, we use surface decoration on nanochannel walls to investigate the influences on fluid motion and further explore the fundamental physical principle of this behavior. To begin with, we designed and fabricated the nanofluidic mixer for the first time, which comprised hybrid surface patterns with different wettabilities on both top and bottom walls of nanochannel. Although microfluidic mixers have been intensively investigated, nanofluidic mixer has never been reported. Without any inside geometric structure of nanochannel, the mixing phenomenon can be achieved by the surface patterns and the mixing length can be significantly shortened comparing with micromixer. We attribute this achievement to the chaotic flows of two fluids induced by the patterned surface. The surface-related phenomena may not be so prominent on large scale, however, it is pronounced when the scale shrinks down to nanometer due to the large surface-to-volume ratio in nanochannel. In the second part of this work, based on the technology of nanofabrication and similar principle, we built up another novel method to control the speed of capillary flow in nanochannel in a quantitative manner. Surface patterns were fabricated on the nanochannel walls to slow down the capillary flow. The flow speed can be precisely controlled by modifying hydrophobicity ratio. Under the extreme surface-to-volume ratio in nanochannel, the significant surface effect on the fluid effectively reduced the speed of capillary flow without any external energy source and equipment. Such approach may be adopted for a wide variety of nanofluidics-based biochemical analysis systems.
