چکیده

The effect of variable thermal conductivity and thermal radiation on heat and mass transfer in the MHD flow of a Casson fluid over a porous stretching sheet is investigated. The governing non-linear partial differential equations for the flow, heat and mass transfer are solved by employing the Runge-Kutta fourth order method along with shooting technique. The velocity, temperature and concentration profiles for different governing parameters are illustrated graphically. It is observed that increase in the yield stress of the fluid results in the reduction of velocity while the temperature and concentration are enhanced. The numerical values of the skin friction coefficient, the Nusselt number and the Sherwood number for different values of physical parameters are analyzed. KeywordsCasson fluid, MHD flow, Heat and Mass transfer, Radiation, Variable thermal conductivity.
