A note on thermal-diffusion and chemical reaction effects on MHD pulsating flow in a porous channel with slip and convective boundary conditions

Abstract

The present note investigates the effects of chemical reaction and Soret effects on hydromagnetic laminar viscous pulsating flow in a porous channel with slip and convective boundary conditions. The governing equations are solved analytically and the expressions for velocity, temperature, concentration, Nusselt number and Sherwood number distributions are obtained. The effects of various pertinent parameters on flow variables have been discussed numerically and explained graphically. Analysis indicates that the temperature distribution decreases for a given increase in heat transfer Biot number and Prandtl number while it increases with an increase in Hartmann number. Further, the concentration distribution increases with an increase in the mass transfer Biot number, Soret number and the heat transfer Biot number, while it decreases for a given increase in the chemical reaction parameter.
