Numerical study of convective heat and mass transfer flow in channels

Abstract

We analyze the combined influence of thermodiffusion and diffusion heat transfer flow of a chemically reacting viscous fluid through a porous medium in a vertical channel under the influence of the transverse magnetic field. The nonlinear coupled equations governing the flow of the heat and mass transfers have been called by using Galerkin finite element analysis with a quadratic approximation function. The velocity, temperature, concentration, and rate of heat and mass transfers are analyzed for the different values of G;M;D - 1;N; Sc;S 0;Du, α and γ. It is found that an increase in S 0 andDu enhances the velocity, temperature, and concentration. An increase in the chemical reaction in γ depreciates a velocity and concentration and enhances a temperature in the degenerating chemical reaction and in the generating chemical reaction case the velocity, concentrations are enhanced and temperature is depreciation.
