Abstract

We have analyzed the MHD flow of a conducting couple stress fluid in oscillating channel with heat and mass transfer. The non-Newtonian fluid under consideration is obeying the Casson model. In this analysis we are taking into account the induced magnetic field. The analytic solution for the problem has been obtained by using homotopy perturbation method for steady and unsteady cases. The distributions, temperature of the velocity and concentration functions are discussed. The effects of the various parameters such as the couple stress parameter, the Hartmann number , the Reynolds number and heat and mass transfer coefficient. It was found that the Darcy’s coefficient for the fluid restrain the velocity. Vise versa Hartmann number , the Reynolds number haste of it.

Keywords: MHD flow, Casson Fluid etc.
