Abstract

Micro/mini channel based circuits with cooling media is one of the most efficient solution for the thermal management of electronic components due to its higher heat transfer coefficient and higher heat transfer surface area per unit volume. Fluid flow and heat transfer characteristics of flow through microchannel under single phase and two phase flow conditions using Aluminium oxide nanofluid is experimentally investigated. An experimental set up with microchannel heat sink has been fabricated and the analysis has been performed for different volume percentage of nanoparticles like 0.001%, 0.01% and 0.1%.The single phase and two phase heat transfer coefficients were found to be high for flow with nanofluid compared to base fluid but with a pressure drop penalty. The single phase heat transfer coefficient increases with increasing concentration of nanofluid. But the two phase heat transfer coefficient increases up to certain value of the volume concentration of nanofluid and then decreases. The critical heat flux also found to be high for the flow with nanofluid than water and is found to be increasing with increasing concentration of nanofluid. The single phase flow results using water as the working fluid are compared with the standard correlations available in the literature and are found to be matching well.
