Abstract:
This work addresses the problem of Magnetohydrodynamic laminar unsteady flow of an incompressible electrically
conducting fluid past an infinite vertical porous plate. It investigates how joule heating affects the velocity and temperature profiles of the fluid flow subjected to transverse magnetic field. The research examines specific equations of
MHD flow which are solved numerically by finite difference approximations, using computer programme. The numerical results of this study reveal that an increase in joules heating parameter causes an increase in the velocity and
temperature profiles uniformly near the plate but remain constantly distributed away from the plate, implying that the
flow field of the MHD free convective flow is influenced substantially by the strength of Joules heating near the wall of
the plate and at the mainstream.
