Abstract
This study represents the numerical solutions of the buoyancy driven laminar and turbulent flows in a two dimensional rectangular enclosure in which one of the vertical walls is heated and the other is cooled. Numerical solutions are obtained for different Reyleigh numbers that range from 104 to 1012 and for different aspect ratios that range from 2 to 12. Low Reynolds number extension of the two equation k-ε turbulent model is used in the solution of turbulent flow (Ra > 108). The results obtained are in good agreement with the experimental results reported in literature. The influence of Rayleigh number on the heat transfer and flow field and the variation of local Nusselt numbers at the hot and the cold walls are presented.
