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.
