“…From the fundamental perspectives, Nield [4] made the first attempt to study the stability of the convective flow in horizontal layers with imposed temperature and concentration gradients. This was then followed by Khan and Zebib [5] in the study of flow stability in vertical porous layer. Trevisan and Bejan [6][7][8] have also conducted a series of investigations of these effects on natural convection for various geometries.…”

In the present paper, an analytical study of the effects of radiation on the buoyancy induced heat and mass transfer by natural convection from an isothermal paraboloid embedded in a saturated porous medium has been done in case of constant temperature and concentration. For the analysis of the problem, an integral method of Von Karman type has been used. The governing parameters for the problem under study are the buoyancy ratio , Lewis number and radiation parameter . The computed results have covered a wide range of the governing parameters. It has been concluded that the local Nusselt number decreases while the local Sherwood number increases for aiding flow for increasing Lewis number. But an opposite trend is observed for opposing flow. The local Nusselt number decreases while the local Sherwood number increases for increasing values of the radiation parameter in case of aiding flow . An opposite trend is observed for opposing flow.

“…Nield [1] made the first attempt to study the stability of convective flow in horizontal layers with imposed vertical temperature and concentration gradients. This was followed by Khan and Zebib [2] in the study of flow stability in a vertical porous layer. An analysis of the mass transfer effect on the free convective transport of a viscous fluid past an infinite vertical porous plate was carried out by Soundalgekar [3].…”

The flow, heat and mass transfer characteristics of the free convection on a vertical plate with uniform and constant heat and mass fluxes in a doubly stratified micropolar fluid saturated non-Darcy porous medium are studied. The nonlinear governing equations and their associated boundary conditions are initially cast into dimensionless forms by pseudo-similarity variables. The resulting system of equations is then solved numerically using the Keller-box method. The numerical results are compared and found to be in good agreement with previously published results as special cases of the present investigation. The effects of the micropolar, Darcy, non-Darcy and stratification parameters on the dimensionless velocity, microrotation, wall temperature, wall concentration, local skin-friction coefficient and wall couple stress coefficient are presented graphically.
