MHD free convective oscillatory Rivlin-Ericksen fluid flow past a porous plate embedded in a porous medium in the presence of heat source with chemical reaction

An analysis is performed to study the unsteady two dimensional MHD free convective oscillatory Rivlin-Ericksen fluid flow of an electrically conducting, incompressible visco-elastic fluid past an infinite vertical porous plate embedded in a porous medium, through which suction occurs with constant velocity and taking into account the effects of both chemical reaction and heat source. A uniform magnetic field is assumed to be applied transversely to the direction of the free stream in the presence of induced magnetic field. The governing equations describing the problem are solved by using the perturbation method. Numerical results for the velocity, temperature and concentration distributions as well as skin friction are obtained and reported in tabular form as well as graphically for several values of pertinent parameters which are of physical and engineering interest. The numerical results of the skin friction of visco-elastic fluid are compared with the corresponding flow problems for an ordinary fluid.
