MAGNETOHYDRODYNAMIC TRANSIENT FLOW THROUGH A POROUS MEDIUM BOUNDED BY A HOT VERTICAL PLATE IN THE PRESENCE OF RADIATION: A THEORETICAL ANALYSIS

The transient magnetohydrodynamic free convective flow of viscous, incompressible, electrically conducting, gray, absorbing–emitting, but non-scattering, optically thick fluid medium which occupies a semi-infinite porous region adjacent to an infinite hot vertical plate moving with a constant velocity is analyzed. A uniform magnetic field is assumed to be applied transversely to the flow. The Darcian viscous flow model for the porous medium is used. The momentum and thermal boundary-layer equations under physically realistic boundary conditions are solved through the use of the Laplace transform technique. The influence of the characteristic parameters of the problem on the velocity, temperature, and shear stress is investigated.
