Abstract
The unsteady MHD flow of visco-elastic fluid past an infinite oscillating porous plate in slip flow regime is investigated. The unsteady equations of the governing flow are solved by perturbation technique for elastic parameter is least. The mathematical expressions for the velocity, temperature, concentration distributions have been derived analytically and also its behaviour is computationally discussed with reference to different flow parameters with the help of graphs. Also the skin friction, the Nusselt number and the Sherwood number are also obtained analytically and their behaviour is discussed computationally.
Keywords: Heat and mass transfer, MHD flows, porous medium, unsteady flows and visco-elastic fluids.
