✏Nanofluids Book Summary : This book presents current research related to the synthesis, characterisation, and heat transfer of nanofluids. Nanofluids are stable colloidal suspensions of solid nanomaterials in base fluids. While nanoparticles were first added to base fluids to obtain nanofluids; other nanomaterials, like nanorods, nanotubes, nanowires, nanofibers, nanosheets, or other nanocomposites, are used to synthesise the nanofluids. The types of base fluids cover a wide range of liquids that include water, oil, ethylene-glycol (automotive antifreeze), refrigerants, polymer solutions, or even bio-fluids. The special properties of nanomaterials and their interactions with base fluids lead to substantially different properties of nanofluids compared with that of base fluids. Significant physical insights into complex physical phenomena in nanofluids are gained via the utilisation of advanced theoretical tools and state-of-the-art experimental measurement techniques.

✏Numerical Simulation of Thermal and Hydraulic Transport of Nanofluids in Minichannels Book Summary : The goals of this dissertation were (i) to investigate the mechanisms behind the thermal conductivity enhancement of nanofluids; (ii) to develop new combined mechanisms based on the analytical thermal conductivity model; (iii) to numerically investigate the fluid dynamics and heat transfer characteristics of nanofluids in a circular tube corresponding to the new analytical thermal conductivity model; (iv) to study the influence of the nanoparticle volume concentration, particle size, base fluid and temperature of nanofluids on the viscosity of nanofluids; (v) to examine the temperature effect on the thermal conductivity enhancement of nanofluids with physical mechanisms behind this enhancement and models; (vi) to investigate the local heat transfer coefficient of nanofluids associated with constant thermophysical properties or temperature dependent transport properties under the uniform heating and cooling condition with laminar flow regimes; and (vii) to investigate the Brownian motion based thermal conductivity model's effects on the channel wall by using a computational fluid dynamic (CFD) toolbox, which is called OpenFOAM, and enlighten how these models alter the temperature gradients at the channel wall as a function of position in the entrance region of an internal flow. Nanofluids are suspensions of nanoparticles (typically 2-100 nm with average particle sizes) in base fluids that are called conventional heat transfer fluids such as water, oil, ethylene glycol and mixtures. They have unique physical properties for practical engineering applications. It is crucial to determine accurate viscosity and thermal conductivity models for the numerical simulation of nanofluids. Both of these thermophysical properties significantly affect the heat transfer performance and pumping power penalties of nanofluids, respectively. Thus, a comprehensive parametric study has been conducted to investigate the most appropriate models by comparing them with the existing experimental data. The most appropriate correlations have been determined and implemented into the OpenFOAM. The numerical results have shown that the Brownian motion based thermal conductivity models are not capable of explaining the thermal conductivity enhancement of nanofluids. In addition, the interfacial layer based thermal conductivity model has been applied to explain the thermal conductivity improvement of nanofluids, and it was observed that the introduction of the nanolayer thickness is still superficial. The intermolecular structure between the solid nanoparticles and base fluid molecules cause an interfacial layer. However, the thickness of this nanolayer may not make an important contribution to increase the thermal conductivity of nanofluids due to unrealistic prediction of the nanolayer and determination of the thermophysical properties of this nanolayer. Thus, a combined mechanism based thermal conductivity model, which consists of the effective medium theory, aggregation based thermal conductivity model and Brownian motion, has been developed to predict the existing experimental data. It was observed that this model closely agrees with the existing experimental data. This new analytical thermal conductivity model has been implemented into the OpenFOAM to investigate its effect on the heat transfer enhancement of nanofluids with using the temperature dependent thermophysical properties.

✏Nanofluids Properties and Their Applications Book Summary : Viscosity, heat transfer and pressure loss measurements of several nanofluids, which are suspensions of nanoparticles less than 100 nm size, in base fluids, e.g. ethylene or propylene glycol and water mixture are presented. The nanoparticles considered here are oxides of aluminum, copper and silicon. Effects of thermophysical properties of nanofluids on the Prandtl number and the Mouromtseff number have been analyzed in detail. Authors show that the Prandtl number increases with increasing particle volumetric concentration, which in turn increases the convective heat transfer coefficients of the nanofluids. Experiments on nanofluids in the turbulent regime show the enhancement of convective heat transfer and pressure loss with an increase in nanoparticles volume concentration. The authors prove that application of nanofluids for heating buildings could result in reduction of volume flow rate of heat transfer fluids, heat exchanger size, and the pumping power. Experiment on a diesel electric generator confirms an increase in the thermal efficiency of the heat recovery from the engine radiator for nanofluids compared to the conventional coolant.

✏Thermal Transport of Nanofluids in a Minichannel Leyuan Yu Book Summary : Nanofluids have been proposed as a promising candidate for advanced heat transfer fluids in a variety of important engineering applications ranging from energy storage, electronics cooling to thermal processing of materials. However, the thermal transport mechanisms for nanofluids are far from being well understood. In particular, a consensus is lacking on if and how the dispersed nanoparticles alter the single-phase and two-phase heat transfer mechanisms of nanofluids in forced convective flows, and the applicability of established fluid mechanics and heat transfer theories for predicting thermal transport of nanofluids has also been called into question. The present research aims at conducting a systematic study of single-phase convective heat transfer and two-phase flow boiling of nanofluids in a circular minichannel. The goals are to experimentally characterize the effective thermophysical properties, pressure drop and heat transfer behaviors of nanofluids with respect to their constituent base fluids, and to explore the effects of the particle-fluid interactions on the convective transport physics in nanofluids. In this work, both aqueous Al2O3-water and non-aqueous Al2O3-Polyalphaolefin (PAO) nanofluids were synthesized. The effective thermophysical properties of the nanofluids, especially the viscosity and thermal conductivity, were first measured and compared to predictions from the effective medium theories (EMTs). Special attention was given to the effects of the nanoparticle size and aspect ratio, the aggregation and the dispersion state of the nanoparticles. Once these effects were considered properly, no abnormal changes were found in the effective thermophysical properties of nanofluids. Then, an experimental investigation was conducted to study the single-phase forced convective heat transfer of the nanofluids through a circular minichannel. The friction factor and convective heat transfer coefficient were measured for the nanofluids over a wide range of Reynolds number, covering the laminar, transition and early stage of fully developed turbulent flows. Some interesting phenomena were observed, such as the developing flow behaviors and delayed transition to turbulence for Al2O3-water nanofluids, and the abnormal heat transfer characteristics of Al2O3-PAO nanofluids, which can be attributed to the nanoparticle-fluid interaction and the shear-induced alignment and orientational motion of nanoparticles. Based on the convective heat transfer experimental data, the thermal performance and effectiveness of nanofluids for practical cooling applications were critically evaluated using different figures of merit (FOM), and it was found the nanofluids do not offer any enhanced thermal performance when the increased pumping power consumption and the negative effect of reduced specific heat on heat transfer are taken into account. And lastly, convective flow boiling and two-phase flow of Al2O3-water nanofluids were studied with an emphasis on the effect of nanoparticle deposition on two-phase flow instabilities. It was discovered the onset of flow instabilities can be suppressed by the nanofluids.

✏Heat Transfer Due to Laminar Natural Convection of Nanofluids Book Summary : This book presents a theoretical study of heat transfer due to laminar natural convection of nanofluids, using Al2O3-water nanofluid as an example. An innovative method of similarity transformation of velocity fields on laminar boundary layers is applied for the development of a mathematical governing model of natural convection with actual nanofluids, and a novel model of the nanofluid's variable thermophysical properties is derived by a mathematical analysis based on the developed model of variable physical properties of fluids combined with the model of the nanofluid's thermal conductivity and viscosity. Based on these, the physical property factors of nanofluids are produced, which leads to a simultaneous solution for deep investigations of hydrodynamics and heat transfer of nanofluid's natural convection. The book also proposes novel predictive formulae for the evaluation of heat transfer of Al2O3-water nanofluid’s natural convection. The formulae have reliable theoretical and practical value because they are developed by rigorous theoretical analysis of heat transfer combined with full consideration of the effects of the temperature-dependent physical properties of nanofluids and the nanoparticle shape factor and concentration, as well as variations of fluid boundary temperatures. The conversion factors proposed help to turn the heat transfer coefficient and rate of fluid natural convection into those of nanofluid natural convection. Furthermore, several calculation examples are provided to demonstrate the heat transfer application of the proposed predictive formulae.

✏Effect of Different Surface Modified Nanoparticles on Viscosity of Nanofluids Book Summary : Resistance to fluid flow creates various problems, and fluid viscosity reduction can effectively control these problems. Hydrophilic TiO2-water and hydrophilic-lipophilic TiO2-water nanofluids were prepared by stirring and ultrasonic mixing; the rotational viscometer was used to measure the viscosity of nanofluids that formed by different surface modifications of nano-titanium dioxide and deionized water. The results show that the viscosity of TiO2-water nanofluid increases with the decrease in the temperature and increase in the mass fraction of nanoparticles, the hydrophilic TiO2-water nanofluids has a slightly larger viscosity than the hydrophilic-lipophilic TiO2-water nanofluids, and the higher the mass fraction of the nanoparticles is, the greater the difference is.

✏Effect of Temperature Jump on Forced Convective Transport of Nanofluids in the Continuum Flow and Slip Flow Regimes Book Summary : Abstract: In this paper, an attempt has been made to extend the modified Buongiorno model of nanofluids originally proposed by Yang et al. (2013a, J. Heat Transf., 135, 054504) from the continuum flow regime to the slip flow regime, in consideration of the effects of both velocity slip and temperature jump near the wall. Since the use of velocity slip boundary condition has been extensively applied and well-understood in the literature, the focus of the present study is on the temperature jump boundary condition. Based on the theoretical results obtained using the Runge–Kutta–Gill method, one can conclude that the temperature jump near the wall has more significant influence on the dimensionless temperature than the dimensionless velocity and volume fraction of nanoparticles in the cross section of a channel. Moreover, the neglect of temperature jump leads to the overestimation of Nusselt number based on the bulk mean nanofluid thermal conductivity Nu B, especially in the slip flow regime. Subsequently, two key parameters of nanofluids, namely Knudsen number Kn and the ratio of Brownian and thermophoretic diffusivities N BT, were discussed in order to investigate their effects on the fluid flow and heat transfer characteristics of nanofluids. The results indicated that the increase of Kn not only enhances heat transfer performance, but also reduces pressure drop, demonstrating the promising prospect of nanofluids applications in micro and nano-scales devices. Furthermore, it is found that the maximum Nu B can be achieved when Kn is around 0.07 or when N BT is around 0.5, which is useful for optimizing nanoparticles for practical applications. Highlights: The modified Buongiorno model of nanofluids was extended to the slip flow regime. The effects of velocity slip and temperature jump near the wall were considered. The neglect of temperature jump leads to the overestimation of Nu B . Optimal Kn and N BT were obtained to achieve maximum heat transfer performance.

✏Performance Evaluation of Nanofluids in an Inclined Ribbed Microchannel for Electronic Cooling Applications Book Summary : Nanofluids are liquid/solid suspensions with higher thermal conductivity, compared to common working fluids. In recent years, the application of these fluids in electronic cooling systems seems prospective. In the present study, the laminar mixed convection heat transfer of different water-copper nanofluids through an inclined ribbed microchannel--as a common electronic cooling system in industry--was investigated numerically, using a finite volume method. The middle section of microchannel's right wall was ribbed, and at a higher temperature compared to entrance fluid. The modeling was carried out for Reynolds number of 50, Richardson numbers from 0.1 to 10, inclination angles ranging from 0° to 90°, and nanoparticles' volume fractions of 0.0-0.04. The influences of nanoparticle volume concentration, inclination angle, buoyancy and shear forces, and rib's shape on the hydraulics and thermal behavior of nanofluid flow were studied. The results were portrayed in terms of pressure, temperature, coefficient of friction, and Nusselt number profiles as well as streamlines and isotherm contours. The model validation was found to be in excellent accords with experimental and numerical results from other previous studies.

✏Parametric Investigation of Nanofluids Utilization in Parabolic Trough Collectors Book Summary : Highlights: The use of nanofluids in parabolic trough collector is investigated. Al2 O3 and CuO nanoparticles in Syltherm 800 are examined. The thermal performance of the collector is increased close to 0.6% with nanofluids. CuO/Syltherm is the best nanofluid for all the examined temperature levels. Significant enhancement proved for high concentration ratio and low flow rate. Abstract: The objective of this study is to investigate the use of nanofluids in parabolic trough collectors for various cases. The two most usual nanoparticles (Al2 O3 and CuO) are examined in the usual thermal oil Syltherm 800. A detailed thermal model is developed in EES (Engineering Equator Solver) and its results are validated with experimental results from the literature. In the first part of the analysis, the Eurotrough ET-150 module is examined for various inlet temperature levels (25–325 °C) for the three examined working fluids. The results prove that both nanofluids are more efficient than the Syltherm 800, with Syltherm 800/CuO to be the best choice. The heat transfer enhancement with the use of nanofluids is proved to be approximately to 50% and this enhancement is greater at higher temperature levels. In the parametric analysis part, the mean thermal efficiency enhancement is determined for various combinations of flow rates and concentration ratios for both nanofluids. The use of CuO is able to increase the thermal efficiency up to 1.26% and the use of Al2 O3 up to 1.13% when the concentration ratio is maximized and the flow rate is relative low.
