Unsteady MHD free convective flow of a casson fluid past over an oscillating vertical plate

In this work chemical reaction and thermal radiation effect on an unsteady MHD casson fluid flow past over an oscillating vertical plate is examined. The resulting system of the equations governing the flow is solved analytically using regular perturbation technique. Expressions for the non-dimensional velocity fields, temperature field, concentration field, the co-efficient of skin friction, Nusselt number and Sherwood number at the plate are obtained and the effects of various parameters entering into the problem on these fields are demonstrated graphically and results are interpreted physically. It is found that the results obtained in the present work are in excellent agreement with the physical reality of the problem.
