Chemical reaction and soret, Dufour effect on radiation-convection flow with porous medium.

This work reports the numerical study of unsteady laminar boundary layer flow of viscous, electrically conducting. incompressible, fluid in a channel filled with a porous medium along with a semi-infinite vertical plate in the presence of uniform mass diffusion and transverse magnetic field. The finite element method, Galerkin is used to solve the governing equations. The flow phenomenon has been calculated with the help of flow parameters such as velocity, temperature and concentration profiles for different parameters such as. Schmidt number, Prandtl number, Magnetic field, Chemical reaction Parameter, Permeability parameter, Chemical reaction, Soret number and Grashof number. The velocity, temperature, and concentration are observed graphically. The coefficient of skin-friction, Nusselt number, and Sherwood number are calculated. [ABSTRACT FROM AUTHOR]
