Hall Effects on Hydromagnetic Free Convection Flow Along a Porous Flat Plate with Mass Transfer

抄録

Effect of Hall current on the unsteady free convection flow of a viscous incompressible and electrically conducting fluid, in presence of foreign gases (such as H₂, CO₂, H₂O, NH₃), along an infinite vertical porous flat plate subjected to a transpiration velocity inversely proportional to the square-root of time is investigated in the presence of a uniform transverse magnetic field. The results are discussed with the effects of the parameters Gc (the Grashof number for mass transfer), m (the Hall parameter) and Sc (the Schmidt number) for Pr=0.71, which represents air.
