COMBINED HEAT AND MASS TRANSFER IN MHD THREE-DIMENSIONAL POROUS FLOW WITH PERIODIC PERMEABILITY & HEAT ABSORPTION

The paper analyzed the effects of mass transfer and heat sink on three-dimensional free convective heat transfer flow through a highly porous medium with periodic permeability, in the presence of transfer’s magnetic field. Assuming the free stream velocity to be uniform, solutions of governing equations of motion are obtained, using finite deference technique, which is more economical from computational view point. The results obtained for the velocity, temperature, concentration, skin friction, rate of heat and mass transfer are discussed and analyzed through graphs, to observe the effects of various flow parameters. It is found that the concentration of the species is higher for small values of Sc and lower for larger values of Sc. Also it is found that heat sink and magnetic field reduces the velocity of the fluid while heat transfer coefficient increases in the presence of heat absorption parameter.
