Abstract

In this study, we compare the heat-conveying capabilities of ordinary water with those of cooling fluids such as Ag-Water, TiO2-water, and Al2O3-water nanofluid at a volume percentage of 0.50%, and we also examine the six flow micro-channels of the fin-equipped heat sink. Hardware like microprocessors and integrated circuits are not used in the comparison. To evaluate the effectiveness of different cooling fluids, a number of thermal metrics are used, such as temperature distribution, convective coefficient of heat transfer, Nusselt number, and heat sink thermal resistance. In this experiment, the ANSYS software tool Fluent (v16.0) is used. For the purpose of solving the partial differential equations controlling the cooling fluid flow and heat transfer, the Finite Volume Method is employed. The numerical results show that cooling all kinds of nanofluids is better than cooling the regular fluid, due to the very high values of the Nusselt number and the convective heat transfer coefficient. Finally, it has been determined that Ag-water nanofluid is a viable option for improving heat transmission in general.
