Abstract

In this study, forced convection heat transfer about a permeable horizontal plate in the presence of magnetic field and thermal radiation effects in the porous medium are investigated. The fluid is assumed to be incompressible and dense. The nonlinear parabolic partial differential equations governing the flow are transformed into the non-similar boundary layer equations. The Keller box method is used to solve these equations. The governing dimensionless parameters arising from dimensionless governing equations are as follows: the porosity epsilon, the inertia parameter gamma, the magnetic parameter Mn, the radiation conduction parameter R-d, the surface temperature parameter theta(w), and the suction/injection parameter f(w). The effects of these parameters on the local skin friction and local heat transfer parameters as well as the velocity and temperature profiles are analyzed. The validity of the solution methodology and the results are questioned by comparing the findings obtained with those available in the literature and, a fairly good agreement is reached.
