Summary
A numerical solution comparing steady natural convection of water and air in a two-dimensional, partially divided, rectangular enclosure is presented. Rayleigh numbers investigated range from 1 to 100 millions, and the opening ratios studied are 0, 1/4, 1/6, and 1/8, respectively. To obtain a comparative study, Prandtl number of 7 (for water) and 0.71 (for air) were used for the two working fluids. The study demonstrates that the conventional use of water to model air convection in partitioned enclosures gives reasonable heat transfer results.
