Abstract

The present work investigated analytically the influence of thermal diffusion and radiation on unsteady MHD, free connective incompressible flow of viscous, electrically conducting fluid past an impulsively moving isothermal porous plate and for the case of ramped wall temperature and ramped wall concentration. The non-dimensional governing equations are solved in closed form by using Laplace transform method. Exact solutions are obtained for velocity, concentration and temperature. With the help of those expressions - Skin friction, Sherwood and Nusselt numbers are derived. Various physical parameters effect on the above flow equations are studied numerically with the assistance of graphs and tables.
