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. 2000 Mathematics Subject Classification: 76W05 Keywords: MHD, free convection, mass transfer, rotating frame, elastico-viscous, porous medium
Highlights
The study of free convective MHD flow of a rotating fluid with mass transfer is of general interest in view of its varied applications in the field of astrophysical and geophysical sciences
Flow through porous media is helpful in the filtration process and to maintain the temperature of a heated body
Several researchers have analyzed a bewildering variety of flows connected to MHD free convection and mass transfer with/without rotation
Summary
The study of free convective MHD flow of a rotating fluid with mass transfer is of general interest in view of its varied applications in the field of astrophysical and geophysical sciences. Such types of problems find their use in the atmospheric and oceanic circulations as well. Das et al (2004) have estimated the effect of free convection and mass transfer on the flow of an elastico-viscous fluid past an infinite vertical porous plate in a rotating porous medium. Israel-Cookey and Sigalo (2003) discussed the unsteady MHD free convection and mass transfer flow past an infinite heated porous vertical plate with time dependent suction. Kim (2000) has reported the unsteady MHD convective heat transfer past a semi-infinite vertical porous moving plate with variable suction
