Heat and Mass Transfer Flow Over an Inclined Plate with Time Dependent Suction

This paper investigates the effects of hall current, heat source and radiation on unsteady MHD two dimensional, laminar, boundary layer flow of a viscous, incompressible, electrically conducting fluid along a semi-infinite inclined plate in the presence of thermal and concentration buoyancy effects. A time dependent is assumed and the radiative flux is described using the differential approximation for radiation. Asymtotic series expansion about a small parameter. is performed to obtain the flow fields. The velocity of the porous plate increases exponentially with time and a variable suction velocity is applied normal to the plate. The governing equations of the flow field are solved using perturbation technique and the expressions are obtained for velocity, temperature and concentration fields. The observations show good agreement with the previous results.
