Parametric Study of Wavy Microchannel Using Nanofluid

Abstract

In the present study, a parametric study of wavy microchannel has been simulated for three dimensional laminar fluid flow and heat transfer behavior using CFD software. Three different amplitude of 0.3, 0.4, and 0.5 mm and constant wavelength of 3 mm wavy microchannel have also been compared with straight microchannel. In wavy microchannel the Dean vortices cause the mixing of fluid in the channel and hence the thermal performance of the heat sink increases considerably. In addition, Al2O3 water-based nanofluid has been introduced as cooling fluid. Volumetric concentrations 0.5, 1.0, 1.5, and 2.0 of Al2O3 water nanofluid has been used for cooling for a heat flux of 20 W/cm2. The result indicates that wavy microchannel might be the potential alternative for high heat flux electronic cooling.
