CFD Investigation of Volume Fraction of Nanofluid on Heat Transfer Rate in Micro Channel Heat Sink

Abstract

Abstract
New methods of removing heat from integrated chips of the electrical devices are very important. Mini channel liquid cooling is the new method by which we can remove heat from electrical devices easily. Uses of nanofluid in the mini channel liquid cooling is the experiment study. We investigated the effect of nanofluid on the heat transfer rate. We also investigated the effect of volume fraction of a nanofluid in the base fluid (like water and ethylene glycol or EG). We also investigated the height of mini channel liquid cooling. We have found the effective height in which they can work effectively even after increasing this height, beyond the effective height there is no increase in the heat transfer, so we have increased the height in effective region for maximum heat transfer. We analyzed the geometry in computational fluid dynamics (CFD) software. We have considered the rectangular channel in which nanofluid flow with the volume fraction of 0.8, 1.6, 2.4, 3.2 and 4% in base fluids. These nanofluids flow in channel with the five-inlet velocity 2 m/s.
