Abstract: 

MicroChannel Heat Sink is one of the efficient technologies, improving the thermal performance. The aim of the present paper is to investigate the nanoparticles size effects on thermal performance of a trapezoidal MCHS numerically. In the present study, employment of Water – Alumina (Al2O3) and Water – CuO nanofluids is modeled using Eulerian – Eulerian two-phase approach. Solving equations of continuity, momentum and energy in the computational domain is performed via Finite Volume Method (FVM) in FLUENT with the accuracy of 10-6. Recently in most studies nanofluids are simulated as a homogeneous fluid, a comparison between the present two-phase models with homogeneous modeling is conducted and it is found that two phase modeling shows 13.8% better performance in comparison with the other case. The results showed that adding of both nanoparticles increases the heat transfer in microchannel and increasing the diameter of the nanoparticles results in a decrease of heat transfer rate as Alumina and Cu-O nano particles, show 6.63% and 5.022% reduction in heat transfer rate, respetively. Also, Alumina nanoparticles have a lower heat transfer coefficient than CuO nanoparticles. Hence, Water - CuO nanofluid is suitable for trapezoid geometry.
