The effect of a centred, square, heat-conducting body on natural convection
in a vertical square enclosure was examined numerically. The analysis
reveals that the fluid flow and heat transfer processes are governed
by the Rayleigh and Prandtl numbers, the dimensionless body size,
and the ratio of the thermal conductivity of the body to that of
the fluid. For Pr=0.71 and relatively wide ranges of the other parameters,
results are reported in terms of streamlines, isotherms, and the
overall heat transfer across the enclosure as described by the Nusselt
number. Heat transfer across the enclosure, in comparison to that
in the absence of a body, may be enhanced (reduced) by a body with
a thermal conductivity ratio less (greater) than unity. Furthermore,
the heat transfer may attain a minimum as the body size is increased.
These and other findings are justified through a careful examination
of the local heat and fluid flow phenomena
