Abstract: Conjugate natural convection in a porous medium saturated with a gas surrounded by the finite thickness solid walls at presence of a local heat source has been numerically analyzed. Boundary problem has been formulated in dimensionless variables such as “stream function – vorticity vector – temperature” and it has been solved by finite difference method. The effect levels of the heat source, the medium permeability, the transient factor and the heat conductivity of the solid walls on flow patterns and heat transfer modes have been determined.

Keywords: conjugate heat transfer, natural convection, porous medium, Boussinesq approximation, heat source.
