Abstract
The magneto hydro-dynamic flows are of great importance in the industries such as food processing, power generation and in investigating the behavior of boundary layer convection. In this article, the magneto hydrodynamic flow of Newtonian fluid in rectangular cavity under the effect of applied magnetic filed is investigated. In the rectangular cavity, three semi circular cylin-ders are placed as obstacles to create unsteadiness in the flow path. Computational fluid dynamics model is built to analyze and observe the flow behavior in presence of 10 Ampere per meter. Fur-thermore, velocity profiles in vertical and horizontal directions, streamlines patterns, pressure dis-tribution profile, vorticity profile, and viscous stress are presented. These profiles are discussed with and without the presence of strong magnetization force and flow behavior is investigated. The model is designed and compute in COMSOL-Multiphysics. It is concluded that presence of high magnetization force enhance the surface velocity to 1.87 m/s in horizontal direction and 0.86 m/s
