Abstract
The purpose of this report is to bring out the natural convection heat transfer characteristics of a finite vertical thick plate on the adiabatic floor, which is surrounded by the constant temperature wall. Numerical results were obtained for the Grashof number in a range of 0.1 to 105, the ratio of hot and cold wall temperature ranging from 0.05 to 1.0 and Plandtl number of 0.71. The effect of interaction on the natural convection fields were investigated. As a result, in case of small wall temperature ratio, when the Grashof number is large, convection fields of the hot wall side and the cold wall side can form each fields independently. On the other hand, as the Grashof number decreased, a fluid from hot wall side flows into convection filed on cold wall side. It was found that negative heat transfer coefficients at upper end of cold wall are calculated.
