• EFFECTS OF THERMAL RADIATION AND HALL EFFECTS ON MHD FREE CONVECTION FLOW OF VISCO-ELASTIC FLUID THROUGH POROUS MEDIUM PAST AN INFINITE VERTICAL POROUS PLATE

Abstract

This study investigates on unsteady MHD free convection flow of a viscous, incompressible and electrically conducting visco-elastic fluid through a porous medium with simultaneous heat and mass transfer near an infinite vertical porous plate under the influence of uniform transverse magnetic field and taking hall current into account. To check the accuracy of the numerical solutions for energy, state and momentum equations are obtained by using the perturbation method for small elastic parameter. The expressions for the velocity, temperature and concentration have been derived analytically and also its behaviour is computationally discussed. The effect of various governing parameters controlling the physical situation is discussed with the aid of line graphs. Significant results from this study are obtained for that velocity, temperature and concentration. The skin friction on the boundary, the heat flux in terms of the Nusselt number, and the rate of mass transfer in terms of the Sherwood number are also obtained and their behaviour computationally discussed. During the course of numerical computation, an excellent agreement was found between the profiles with z and time series profiles.
