Numerical Modelling of Nanofluid Based Microchannel Heat Sink

Abstract

The present paper describes the effect of heat transfer and fluid flow characteristics of rectangular microchannel under laminar flow conditions. Three dimensional model is created and simulated by applying suitable boundary conditions in the commercial CFD package ANSYS. Two microchannels with width 500 m and 300 m are considered for the present study. Water and nanofluid are chosen as working fluids. Two-phase mixture model is used for the modelling of microchannel working with nanofluid. Numerical model have been validated with the available experimental work in the literature. Then, the simulations were carried out for two different channels with nanofluid as working fluid. Heat transfer and flow characteristics of microchannels with nanofluid as working fluid have been obtained for different nanofluid volume concentrations. Finally, the comparison studies between water and nanofluid have been presented in order to understand the effective use of nanofluid as the heat transfer fluid.
