A theoretical study of heat and mass transfer in forced convective chemically reacting radiating MHD flow through saturated porous medium over fixed horizontal channel

Abstract

In the present study; the effect of chemical reaction, viscous dissipation are considered in the steady forced convective chemically reactive radiating MHD flow through the horizontal channel with joule heating. The channel is saturated with uniform porous medium and having a insulated, impermeable bottom wall. The governing equations for velocity, temperature and concentration field are obtained and solved. The effect of various physical paramteres over these fluids are considred and showed through graphs. The expression for mean velocity, mean temperature and mean concentration are also presented. The numerical values of Nusselt number, skin-friction & Sherwood number are discussed through the table. It was concluded that; for high depth porous medium channel the flud mean temperature and species mean concentration both rise high. Fluid flow can be made fast in this geometrical fluid flow by increasing the depth of the porous medium
