Heat Transfer Enhancement in Microchannel Using Nanofluids

Abstract:

Numerical investigation of heat transfer enhancement in two-dimensional microchannel heat sink (MCHS) using Al₂O₃-water, CuO-water and TiO₂-water was conducted. The effect of different type of nanoparticles at particle volume concentration of 1%, 2% and 5% on the thermal performance in the MCHS was examined. The thermal performance is increased when nanofluids with high thermal conductivity and low dynamic viscosity was used. As the particle volume concentration increases, the heat transfer performance also improved. The result shows that the heat transfer performance of all the nanofluids used in this study was better than that of pure water. Overall, nanofluids with Al₂O₃-water at 5% particle volume concentration show the best cooling performance.
