The steady free convective flow and mass transfer of a rotating elastico-viscous electrically conducting fluid through a porous medium occupying a semi infinite region of space bounded by an infinite vertical porous plate in presence of a transverse magnetic field with constant suction and heat flux is considered. A Cartesian co-ordinate system rotating uniformly with the fluid in a rigid state of rotation with a constant angular velocity Ω about z-axis is chosen. The temperature and the species concentration at the free stream are assumed to be constant. The expressions for velocity, temperature and concentration of the flow field are obtained analytically and the effects of the flow parameters on the flow field are discussed with the aid of graphs.

Abstract


The steady free convective flow and mass transfer of a rotating elastico-viscous electrically conducting fluid through a porous medium occupying a semi infinite region of space bounded by an infinite vertical porous plate in presence of a transverse magnetic field with constant suction and heat flux is considered. A Cartesian co-ordinate system rotating uniformly with the fluid in a rigid state of rotation with a constant angular velocity Ω about z-axis is chosen. The temperature and the species concentration at the free stream are assumed to be constant. The expressions for velocity, temperature and concentration of the flow field are obtained analytically and the effects of the flow parameters on the flow field are discussed with the aid of graphs.
