Optical Study of Natural Convection in an Enclosed Cavity

摘要

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)
