Abstract Complex heat transfer in an enclosure filled with diathermanous medium has been numerically analyzed. The domain of interest is a gas cavity bounded with the heat-conducting solid walls of finite thickness having diffuse grey inner surfaces. The boundary problem has been formulated in dimensionless variables such as ''stream function-vorticity-temperature'' and it has been solved by finite difference method. The effect levels of the Rayleigh number, the surface emissivity and the thermal conductivity ratio on flow patterns and heat transfer modes have been determined.
