ABSTRACT

This study investigates mixed convection heat transfer about an impermeable inclined plate in the presence of magneto- and thermal radiation effects in a porous medium. The fluid is assumed to be incompressible and dense. The nonlinear coupled parabolic partial differential equations governing the flow are transformed into the non-similar boundary layer equations, which are then solved numerically using the Keller box method. The effects of porosity ε, mixed convection parameter Ri, angle of inclination α, magnetic parameter M, and radiation-conduction parameter Rd on the velocity and temperature profiles as well as on the local skin friction and local heat transfer are presented and analyzed. The validity of the methodology and analysis is checked by comparing the results obtained for some specific cases with those available in the literature.
