ON ENTROPY IN BUOYANT MHD RADIATIVE FLOW PAST A VERTICAL PLATE EMBEDDED IN POROUS MEDIUM

The paper presents entropy generation analysis for the radiative MHD buoyant boundary-layer flow past a vertical plate embedded in a fluid saturated porous medium. The plate bears a uniform temperature T-w and the uniform temperature of the fluid far away from the plate is T-infinity. A Cartesian coordinate system is chosen where the x-axis is taken along the vertical plate directed upwards and the y-axis is taken perpendicular to the plate. A uniform magnetic field B is applied normal to the plate. The flow is primarily caused by the density variation impressed upon by the temperature difference. A similarity transformation followed by Runge-Kutta scheme together with shooting method is employed to solve the governing equations. Numerical calculations of quantities of interest conducted for various sets of parameters values are portrayed graphically, in tabular form and discussed.
