Abstract
This paper deals with the study of the heat and mass transfer characteristics of natural
convection from a horizontal surface embedded in a radiating fluid saturated porous medium.
Similarity solutions for buoyancy induced heat and mass transfer from a horizontal surface,
where the wall temperature and concentration are a power function of distance from the origin,
are obtained by using an integral approach of Von Karman type. The effects of the governing
parameters such as buoyancy ratio, Lewis number, radiation parameter and the power-law
exponent on local Nusselt and local Sherwood numbers have been investigated both numerically
and graphically.
