Experiment and flow visualization are conducted in a water-filled cavity which cover the range of Ra=1×10〓----6×10〓 and Pr=3. 3---6. 5. Similarity theorem is applied in analytical investigations. And core region stratification effects to heat transfer are studied. By using scale analysis, temperature and velocity profiles in turbulent natural convection boundary layer are obtained. The results reveals that for turbulent natural convection in enclosures, the bulk of the cavity fluid is essentially statement with thermally stratified temperature and the only substantial motion is that in the boundary layer along four side walls.

在实验方面，作者在高Ra范围内（Ra〓=1×10'~Ra〓=6×10〓，Pr=3.3~6.3）对封闭空间实验台以蒸馏水为介质进行了换热实验与流动显示；在理论分析方面，作者采用相似原理导出了分析解；研究了核心区温度分层规律及其对换热的影响；另外还运用尺度分析法探讨了紊流自然对流边界层温度与速度分布。
