Radiation Absorption Effect on MHD Dissipative Fluid Past A Vertical Porous Plate Embedded in Porous Media

摘要

In this manuscript, an attempt is made to study the radiation absorption effect on MHD dissipative fluid past a vertical porous plate embedded in porous media; under the influence of a uniform magnetic field applied normal to the surface is studied. The governing equations are solved analytically using a regular perturbation technique. The expression for velocity, temperature and concentration fields are obtained with the aid of these, the expressions for the coefficient of skin friction, the rate of heat transfer in the form of Nusselt number and the rate of mass transfer in the form of Sherwood number are derived. Finally the effect of variation of physical parameters on the flow quantities is studied with the help of graphs and tables. It is observed that the velocity and concentration increase during a generative reaction and decrease in a destructive reaction. The same is observed to be true for the behaviour of the fluid temperature. The presence of magnetic field and radiation diminishes the velocity and also the temperature.
