Effects of Free Convection on the Hydromagnetic Accelerated Flow Past a Vertical Porous Limiting Surface (The contributions do not constitute a part of the Proceedings.)
Abstract
The effects of free convection on the accelerated flow of a viscous, incompressible and electrically conducting fluid (e.g. of a stellar atmosphere) past a vertical, infinite, porous limiting surface (e.g. of a star) in the presence of a transverse magnetic field, is considered. The magnetic Reynolds number of the flow is taken to be small enough, so that the induced magnetic field is negligible. Expressions for velocity and skinfriction are obtained by using Laplace transform, when the Prandtl number is equal to one (P=1). Graphs showing variations of velocity and skinfriction, for different values ofG (Grashof number) andM (magnetic parameter) are plotted, and the results of them are discussed.
