The present paper deals numerically with natural convective heat transfer in a confined rectangular cavity of a relatively low geometric aspect-ratio H/W (H, W : height and width of cavity) with different vertical wall temperatures. The numerical calculations using the Up-Wind finite difference method are carried out for a confined rectangular cavity having H/W=0.03〜1,Prandtl number Pr=1〜10^3 and Rayleigh number Ra=10^2〜10^6. The results obtained indicate that the geometrical aspect-ratio H/W significantly affects the rate of heat transfer through the fluid layer. Moreover, useful and convenient correlations of the heat transfer through the fluid layer are derived from the results.
