HYDROMAGNETIC MIXED CONVECTIVE HEAT AND MASS TRANSFER THROUGH A POROUS MEDIUM IN A CYLINDRICAL ANNULUS WITH HEAT SOURCE/SINK

Abstract

We analyze the Soret effect on mixed convective heat and mass transfer through a porous medium confined in a
cylindrical annulus under a radial magnetic field. Two cases have been discussed by considering constant heat
source/sink and heat generating sources in the energy equation. We also take the dissipative effects into account.
The equations governing the flow, heat and mass transfer have been solved by a perturbation technique. The Soret
effect and the dissipative effect on the velocity, temperature and concentration have been depicted through various
profiles. The shear stress, the rate of heat and mass transfer have been evaluated numerically for variations in
the parameters G, D 1 , R, N, Sc and S0.
