• The purpose of this study is to investigate the natural convection heat transfer characteristics of a vertical thick plate of finite height surrounded by a solid wall. The vertical thick plate was mounted on an adiabatic floor. One vertical side of the plate was kept cold and the other side hot. Numerical results were obtained for the Grashof number in the range of 0.1 to 10^5, the ratio of hot to cold wall temperature ranging from 0.05 to 1.0. Furthermore, the effect of mutual interferences of natural convection fields on both walls was investigated. Consequently, in the case of a small temperature ratio, when Gr becomes large, convection fields on the hot- and cold-wall sides become fully independent fields that do not interfere with each other. On the other hand, fluid flow from the hot-wall side invades the cold-wall side with decreasing Gr, resulting in an endothermic phenomenon.
