Viscous Dissipation and Mass Transfer Effects on the Unsteady Free Convective Flow of an Electrically Conducting Viscous Fluid past an Accelerated Vertical Porous Plate with Variable Suction

摘要

Effects of mass transfer and the heat due to viscous dissipation on the unsteady free convective flow of an electrically conducting and viscous, incompressible fluid around a uniformly accelerated infinite vertical porous plate subjected to a suction/injection proportional to (time)sup(-1/2) in the presence of a transverse magnetic field have been investigated. An analytical solution for the velocity and the temperature distributions, and the skin-friction and rate of heat transfer are obtained for small magnetic parameter. During the course of the discussion the effects of the Grashof number, Gr, the modified Grashof number based on the concentration difference, Gc, the Eckert number, Ec, and the suction/injection parameter, a, have been considered, for unit values of the Prandtl number, Pr, and the Schmidt number, Sc.
