Simulations for MHD mixed convection in a partially heated lid-driven chamfered enclosure

Abstract

This study investigates the hydrodynamic convective heat transport mechanism in a chamfered square-shaped cavity filled with water. The upper edge of the cavity is presumed to be at low temperature and moving with constant speed. The mean position of the lower boundary is at higher temperature. The chamfered parts and the remaining edges of the enclosure are thermally isolated and fixed. The flow situation and heat distribution experience variations in response to different magnetic field orientations. This physical configuration exhibits mathematical translation via partial differential equations, which are solved numerically using the Galerkin finite element technique. The findings after simulation are visualized through contour plots and line graphs. The primary goal of this research is to examine the effects of Grashof number, Reynolds number, magnetic field strength, and inclination angle on the flow field and temperature distribution. Our findings provide valuable insights into the mechanisms of mixed convection and heat transfer in chamfered square-shaped cavities under the influence of magnetic fields. It is noted that magnitude of Nusselt number versus Reynolds number decrease from to as Hartmann number increases from to The enhancement in Nusselt number magnitude from upto is aloso observed when Reynolds number rises from upto
