Magnetohydrodynamics and Radiation Effects on the Flow due to Moving Vertical Porous Plate with Variable Temperature

The combined effects of magnetohydrodynamics and thermal radiations on unsteady flow of an electrically conducting fluid past an impulsively started infinite vertical porous plate with variable temperature is investigated. A magnetic field of uniform strength is applied along an axis perpendicular to the plate. The plate temperature is raised linearly with time. An exact solution is obtained by Laplace transformation technique. The dependence of the amplitude of velocity and skin-friction on various parameters are discussed in detail with the help of graphs.
