JP Journal of Heat and Mass Transfer

Abstract:
This paper theoretically analyzes the unsteady flow of a viscous incompressible electrically conducting fluid past an infinite hot vertical non-conducting porous plate embedded in a porous medium with mass transfer in presence of constant suction, periodic variation of plate temperature and a transverse magnetic field. The expressions for the velocity, temperature, skin friction and rate of heat transfer in terms of Nusselt number are obtained using perturbation technique assuming the Eckert number as the perturbation parameter. The effects of the magnetic parameter M, Grashof number for heat transfer

permeability parameter

Schmidt number

Prandtl number

Eckert number

etc. on velocity, temperature and concentration profiles of the flow field and also on the skin friction and rate of heat transfer are studied with the help of figures and tables.

Keywords and phrases: hydromagnetic, free convection, mass transfer, porous, variable temperature.
