An experimental study of natural convective heat transfer in a two-dimensional enclosed cavity was conducted with various cavity geometries. The square cavity was divided by a vertical or diagonal partition. Convective heat transfer rates were determined from interferograms. Heat transfer was reduced by partitioning, but by less than 50. Effects of left and right diagonal partitions were temperature dependent. This was attributed to the presence of complex radiation effects. Author
