Abstract

The study of heat and mass transfer is of great practical importance to engineers and scientists because of its almost universal occurrence in many branches of science and engineering. The effect of porosity parameter and buoyancy ratio parameter for aiding and opposing flows in MHD stokes problem for the flow of an electrically conducting, incompressible, viscous fluid past an impulsively started infinite vertical plate in the presence of variable temperature and uniform mass diffusion. The governing equations dimensionless forms are solved using the Laplace transform technique. In this paper, Solutions for the velocity and skin friction are obtained for different porosity parameter and multiple buoyancy effects for adding and opposing flows.
