RADIATION AND CHEMICAL REACTION EFFECTS OF HEAT AND MASS TRANSFER ON CONVECTIVE MHD SLIP FLOW WITH VARIABLE VISCOSITY IN POROUS MEDIA

Abstract

 The study investigated radiation and chemical reaction effects of heat and mass transfer on convective Magnetohydrodynamics (MHD) slip flow in a porous medium over exponentially-stretching sheet in the presence of variable viscosity and heat generations. The governing boundary layer equations of the model were transformed to a system of ordinary coupled differential equations. The coupled system of equations were then solved numerically by a fourth order Runge-Kutta method along with shooting technique.Aparametric study on the effect of variations in the fluid parameters on velocity, temperature and concentration were conducted and presented graphically. Also, the effects of radiation, magnetic field, thermal and solutal grashof parameters, pranddtl, schmidt and chemical reactions on heat and mass transfer as well as their effects on skin friction, Nusselt and Sherwood number on the fluid parameters were verified and discussed in detail. The findings include the numerical results of variation in Skin friction, Nusselt number and Sherwood number which explain the exponential velocity of the fluid flow, temperature of the energy as well as exponential concentration from which the chemical reaction effects were verified.
