Thermal Radiation Effects on Hydromagnetic Mixed Convection Flow along a Magnetized Vertical Porous Plate

Abstract

Aim of the present work is to investigate the effect of radiation on steady mixed convection boundary layer flow of viscous, incompressible, electrically conducting fluid past a semi-infinite magnetized vertical porous plate with uniform transpiration and variable transverse magnetic field along the surface. The equations governing the flow magnetic and temperature field are reduced to dimensionless convenient form using the free variable transformations and solved numerically by using finite difference method. Effects of physical parameters like Prandtl number, Pr, the conduction-radiation parameterRd, magnetic field parameterS, magnetic Prandtl numberPm, mixed convection parameterλ, and the surface temperature,θwon the local skin friction coefficientCfx, local Nusselt number,Nux, and coefficient of magnetic intensity,Mgxagainst the local transpiration parameterξare shown graphically. Later, the problem is analysed by using series solution for small and large values ofξ, and the results near and away from the leading edge are compared with numerical results obtained by finite difference method and found to be in good agreement.
