Effect of Ohmic heating on magnetohydrodynamic flow with variable pressure gradient: a computational approach

Abstract

ABSTRACT Ohmic heating, which significantly affects magnetohydrodynamic flow, is one of the exciting effects to be experienced. This study looks at the significance of Ohmic heating on two-dimensional flow and dissipative heat transfer of a viscous fluid over a flat surface. The mainstream flow is subjected to a pressure gradient and externally oriented inclined magnetic field. An implicit finite difference method has been used to obtain the convergent solutions and the graphical results have been obtained using MATLAB software. A positive correlation is found between temperature and viscous dissipation parameter. Further, the flow encountered higher resistance due to the magnetic field, which is more prominent when the magnetic field is normal to the flow direction .
