Heat Transfer Enhancement Using Nanofluid Flow in Microchannels: Simulation of Heat and Mass Transfer focuses on the numerical simulation of passive techniques, and also covers the applications of external forces on heat transfer enhancement of nanofluids in microchannels. Economic and environmental incentives have increased efforts to reduce energy consumption. Heat transfer enhancement, augmentation, or intensification are the terms that many scientists employ in their efforts in energy consumption reduction. These can be divided into (a) active techniques which require external forces such as magnetic force, and (b) passive techniques which do not require external forces, including geometry refinement and fluid additives. Gives readers the knowledge they need to be able to simulate nanofluids in a wide range of microchannels and optimise their heat transfer characteristics Contains real-life examples, mathematical procedures, numerical algorithms, and codes to allow readers to easily reproduce the methodologies covered, and to understand how they can be applied in practice Presents novel applications for heat exchange systems, such as entropy generation minimization and figures of merit, allowing readers to optimize the techniques they use Focuses on the numerical simulation of passive techniques, and also covers the applications of external forces on heat transfer enhancement of nanofluids in microchannels

Highlights: Al2 O3 -water is preferred since it has the highest in heat transfer coefficient. SiO2 -water has the highest value of pressure drop whereas water has the lowest. Al2 O3 -water (working fluid) in MCHS has the lowest value of thermal resistance. MCHS performance enhances well as volume fraction is increased and the nanoparticle size is decreased. Increasing volume fraction and decreasing nanoparticle diameter leads to thermal resistance improvements. Abstract: This paper describes the numerical modelling of heat transfer and fluid flow characteristics for various types of nanofluids and water passing through a microchannel heat sink (MCHS). The microchannel heat sink is of hexagonal shape, with a hydraulic diameter, Dh, of 170μm. In consideration of cases under cooling and heating, the heat flux is fixed to qw =500kW/m 2 . Water was used as the base fluid for various nanoparticles—i.e., Al2 O3, CuO, SiO2 and ZnO- with different volume fractions and nanoparticle diameters. The results implied that nanofluids enhance the thermal performance of the microchannel heat sink by increasing the pumping power. It was also discovered that Al2 O3 -water shows the lowest readings in dimensionless temperature and thermal resistance, while displaying the highest in heat transfer coefficient. Thermal performances of the MCHS can be increased with an increase in volume fraction and by applying smaller particular diameter but at the cost of pumping power and pressure, which would then diminish the overall favourable effects. Ultimately, Al2 O3 -water with 4% volume fraction and 25nm nanoparticles diameter is the favoured nanofluid through microchannel heat sinks and can be adopted in next generation cooling devices.
