Heat source and chemical effects on MHD convection flow embedded in a porous medium with Soret, viscous and Joules dissipation

This present study investigates the effects of Soret and heat source on steady MHD mixed convective heat and mass transfer flow past an infinite vertical plate embedded in a porous medium in the presence of chemical reaction, viscous and Joules dissipation. The governing system of partial differential equations is transformed to dimensionless equations using dimensionless variables. The dimensionless equations are then solved analytically using perturbation technique. With the help of graphs, the effects of the various important parameters entering into the problem on the dimensionless velocity, dimensionless temperature and dimensionless concentration fields within the boundary layer are discussed. Also the effects of the pertinent parameters on the skin-friction coefficient and rates of heat and mass transfer in terms of the Nusselt and Sherwood numbers are presented numerically in tabular form.
