Effects of a conducting body on natural convection in an enclosure with a heat source at the bottom surface was studied numerically. It was found that the thermal conductivity of the body affected the flow pattern and heat transfer. At a Grashof number of 50000, the Nusselt number for a conducting body remained almost as high as for no body, while it decreased remarkably when the body was adiabatic. At a Grashof number of 200000, the difference in the thermal conductivity resulted in different flow patterns, although it had a little effect on the Nusselt number.
