Summary:

In this work CuO nanoparticles are synthesized using sol gel technique and water based nano fluids of two different volume concentrations are prepared. Thermal conductivity and viscosity are measured. A copper heat sink having rectangular macro channels is used for the heat transfer study. Enhancement convective heat transfer and pressure drop are studied experimentally in turbulent flow regime. * Synthesis of CuO nanoparticles * Preparation of CuO/water nano fluid * Convective heat transfer studies in electronic heat sink * Pressure drop and pumping power determination of Nanofluids and comparison with water * Development of correlation of Nusselt number and friction factor
