The present study deals with the two dimensional steady laminar forced MHD Hiemenz flow past a flat plate in a porous medium. The effects of thermal radiation and partial slips on the flow field have been investigated under the variable wall temperature condition of the plate. The governing equations have been transformed into a set of coupled non-linear ordinary differential equations (ODEs) by using suitable similarity transformations. These equations have been solved analytically by using homotopy analysis method (HAM). The effects of Prandtl number, suction/blowing parameter, permeability parameter, velocity slip parameter, radiation parameter, magnetic parameter, wall temperature exponent and thermal slip on velocity and temperature profiles have also been studied graphically. Our results have been validated with the help of results that have already been published.

“…This approximation is valid at points optically far from the boundary surface, and is good only for intensive absorption, that is, for an optically thick boundary layers. Despite these shortcomings, the Rosseland approximation has been used with success in a variety of problems ranging from the transport of radiation through gases of low density to the study of the effects of radiation on blast waves by nuclear explosion, Ali et al [24]. To solve the above equations, the following non dimensional variables are used…”

The free convective boundary layer flow, heat and mass transfer across an isothermal cylinder in the diffusing species is investigated. The partial differential conservation equations are non-dimensionalized and solved numerically by using an implicit iterative tridiagonal finite-difference method. The effects of radiation parameters on dimensionless velocity, temperature and species concentration distributions are studied, for the case of water (Pr = 7.0), concentration is slightly affected by radiation parameter; Temperatures are however increased by an increase in radiation parameter. Furthermore, the local skin friction, local Nusselt number and local Sherwood number have been analyzed for various parametric conditions. It is found that as the thermal radiation parameter increases the skin-friction coefficient increases and the local Nusselt number decreases. Excellent agreement is obtained with the earlier studies for the purely fluid.

“…The effects of thermal radiation in different geometries have been discussed by several authors. Chen et al [22] studied the effects of radiation interaction in the boundary layer flow over a horizontal surface. Arpaci [23] , Cheng and Ozisik [24] , and Sparrow and Cess [25] showed the thermal radiation effects with free convection from a vertical heated plate.…”

The computational study of the combined effects of radiation and hydromagnetics on the natural convection flow of a viscous, incompressible, and electrically conducting fluid past a magnetized permeable vertical plate is presented. The governing non-similar equations are numerically solved by using a finite difference method for all values of the suction parameter ξ and the asymptotic solution for small and large values of ξ. The effects of varying the Prandtl number P r, the magnetic Prandtl number P rm, the magnetic force parameter S, the radiation parameter R d , and the surface temperature θw on the coefficients of the skin friction, the rate of heat transfer, and the current density are shown graphically and in tables. An attempt is made to examine the effects of the above mentioned physical parameters on the velocity profile, the temperature distribution, and the transverse component of the magnetic field.
