RADIATION ABSORPTION AND VISCOUS-DISSIPATION EFFECTS ON MAGNETOHYDRODYNAMIC FREE-CONVECTIVE FLOW PAST A SEMI-INFINITE, MOVING, VERTICAL, POROUS PLATE
RÉSUMÉ
This article investigates radiation absorption and viscous-dissipation effects on magnetochydrodynamic free-convective flow past a semi-infinite, moving, vertical, porous plate, with heat generation and chemical reaction (Kr). Flow is unsteady and restricted to the laminar domain. The dimensionless governing equations for this investigation are solved analytically using multiple regular perturbation law. The effects of various physical parameters on velocity, temperature (T), and concentration (C) fields are presented graphically. With the aid of the graphs, expressions for skin friction, Nusselt number, and Sherwood number profiles are provided with the use of tables. We find that increases in Kr, Schmidt number (Sc), Prandtl number, and thermal radiation results in decreased velocity and T. In addition, increases in both Kr and Sclead to decreased C. However, increases in porous medium, solutal Grashof number, and radiation lead to increases in both velocity and T.
