by R.Swetha N.Chaturvedi G.Viswanatha Reddy S.Vijaya Kumar Varma

Abstract:
In the present article, the analytical solution of MHD dissipative and free convective boundary layer flow past a porous vertical surface under the influence of uniform magnetic field in the presence of thermal radiation, heat absorption chemical reaction and thermal diffusion is studied. The said study has been carried out in two cases of boundary conditions;1) when the plate is subjected to suction with constant velocity and 2) when the permeable plate has a moving velocity in the direction of fluid flow. The governing equations are solved by using a perturbation technique by making some simplifying assumptions. The solutions for temperature, concentration and velocity are obtained and presented in graphs. Also, the exact solutions for the temperature, concentration and velocity fields in the form of heat and mass transfer rates, shear stress are obtained and presented in tables. The effects of various flow parameters on concentration, temperature, velocity are analyzed and illustrated graphically and the effects of their gradients are shown through tables. The present study has a wide range of applications in Science and Technology. The problem under consideration can further be studied for different positions of the plate with variable suction.
