Design and heat transfer performance analysis of mini-channel heat sink with water, EG and EG20 based nanofluids-computational approach

A numerical investigation is performed for cooling of mini-channel heat sink in rectangle shape for constant heat flux condition. The heat sink is analyzed for five different Reynolds number and using Al2O3 nanoparticle with Water and EG as a basic fluid. ANSYS Fluent is used for numerical computations using a single phase model. Also, validation of results, for different values of Reynolds number, with experimental data is done. Other parameters such asheat resistance, Nusselt number, pumping power and coefficient of heat transfer and channel temperature variation are identified and analyzed. The results show that when Reynolds Number increase in the concentration of Al2O3 nanoparticle the Nusselt number is increased sharply except for EG for lower values of Re and the thermal resistance is decreased while at the same time the pumping capacity increases. From the Simulation Results and comparison of all Re and Ø (Fraction of Nano Particle in Percent) with given three base fluids combination, it can be noted that Al2O3, Al2O3 + EG20 nanofluid have more cooling capacity. As with Ø = 5% in Al2O3 + EG20, Nu increases by 47.8% and Coefficient of heat transfer increases by 3.05%, also it shows the power required by pump is less.
