Abstract

The effects of radiative heat transfer on the fully developed free convection flow of a viscous incompressible fluid-saturated porous medium between two vertical walls in the presence of a uniform gravitational field have been studied. An exact solution of the governing equations has been obtained. Radiation is found to have significant effects on the velocity field and temperature distribution. It is observed that the fluid velocity decreases with an increase in either radiation parameter or porosity parameter. It is also observed that the velocity at any point in the flow region increases with an increase in Grashof number. The effect of thermal radiation on temperature field is also analyzed. The fluid temperature increases with an increase in either radiation parameter or temperature parameter.
