Abstract
Cooling of electronic equipments is playing an important role in the last decades as a world experiences a technological boom in all fields. In this study, a numerical study for mixed convection cooling of microprocessor is investigated by the use of pure water and CuO-water nanofluid at six different volume concentrations. The model is built, meshed and simulated by Ansys Fluent Package 16.0 and a mesh independence test is carried out. The study is performed by changing heat load (115W, 130W), inlet velocity, at different concentrations of nanofluids (Pure water, 0.5%, 0.86%, 1.5%, 2.25%, 3.5%, 5%). The present results showed that using CuO-water nanofluids over pure water provides an enhancement in heat transfer characteristics. The dimensionless parameters such as Nusselt number, Archimedes number, Prandtl number, friction factor and dimensionless temperature are studied and correlated. An enhancement of 36.5% in thermal hydraulic performance is found at 0.50% volume fraction at Re = 1679.212. The data are correlated with maximum error of 4.1%.

Summary
NANOFLUIDS are regarded for a heat transfer medium, because of their great thermal performance. The heat transfer coefficient, pressure loss, friction coefficient, and Nusselt number are all calculated and studied He et al [12] investigated thermal improvement techniques in various structural micro heat sinks. Hassan et al [14] studied the experimental methodology tested outdoors in Taxila, Pakistan to lower PV (Photovoltaic) temperature with the simultaneous use of nanofluid (graphene/water) and phase change material (RT35HC) Performance of this hybrid PVT system in terms of PV temperature, electric efficiency, thermal efficiency and overall efficiency, was compared with PVT/PCM (Phase Change Materials) system integrated with water flowing through tubes inside PCM, PV/PCM system and conventional PV. Mukesh Kumar and Arun Kumar [17] calculated the rate of heat transfer, temperature rise, Nusselt number, thermal resistance, power output, and accuracy of a ship in a six-channel heat source using water and Al2O3/water nanofluids as coolants. It is clear that using of nanofluids in cooling processes are very valuable point of interest especially for cooling of microprocessor due to large usage of it at last decades
