Abstract

There are many under going researchs for the natural convection and fluid flow in rectangular enclosure. In this paper, the optimal model that is the most frequently used for the analysis of a turbulent natural convection in rectangular enclosure is suggested by comparing with the result of Cheesewright's experiment. As We can see the distribution of the velocity, temperature, and turbulent kinitic energy, ST model tends to exaggerate the result of the experiment. The LS model generates better experimental result than the ST and DA's. Therefore, it is resonable to adopt the LS model that contains explicit physical meanings of each term in eouation of turbulent kinitic energy.
