Effects of chemical reaction and radiation absorption on unsteady MHD free convection flow of Jeffery fluid in vertical porous plate

Abstract

In this paper, the investigation on the unsteady MHD free convection flow of Jeffrey fluid in vertical porous plate with chemical reaction and Radiation absorption effects has been carried out.*The governing differential equations of the flow characteristics are evaluated analytically by adoption of the regular perturbation technique. The results obtained for the velocity, temperature and concentration were analysed. The effects of different physical parameters on the flow fields appear on the present situation such as Jeffrey fluid parameter (β), chemical reaction (Kr), Radiation absorption (D), Prandtl number (Pr), Schmidt number (Sc), thermal Grashof number (Gr), mass Grashof number (Gc), magnetic field (M), Heat sink (δ), were illustrated with the aid of graphs in detail. It has been pointed out the fluid velocity significantly deteriorates as the value of Grashof number (Gr), mass Grashof number (Gc), Jeffrey fluid parameter (β), increased, while the opposite trend is noticed for growing values of magnetic field parameter (M), chemical reaction (Kr), Prandtl number (Pr), Radiation absorption (R), Schmidt number (Sc) and Heat sink (δ), respectively.
