Influence of Radiation on Double Diffusive Flow in A Porous Medium Embedded with Vertical Plate


Porous medium
Darcy flow
Vertical Plate
Double diffusion
Natural Convection


Coupled heat and mass transfer in a saturated porous media supported by a vertical plate is analyzed. The fluid inside the porous medium is assumed to be governed by Darcy law. The combined effect of natural convection and radiation on heat and mass transfer inside the medium is investigated. Finite element method is applied to solve the governing equations. Influence of radiation parameter, Lewis number and buoyancy ratio on Nusselt number and Sherwood number is investigated. Both aiding and opposing flow is considered for a wide range of radiation parameter, Lewis number and Rayleigh number.
