Turbulent Natural Convection in Enclosures: 1992 Workshop Revisited


 The objective of this paper is to provide an improved finite-volume numerical method for turbulent natural convection in a vertical differentially-heated square enclosure for the benchmark problem in the 1992 Workshop (Eurotherm Seminar n° 22). The specific purpose here is to identify difficulties associated with the use of the QUICK scheme in solving all the governing equations, including those for k and ∈, and to demonstrate that our algorithm provides accurate calculations without the observed difficulties. A computational logic has been developed to insure the presence of positive source terms, resulting in very stable results with the use of the QUICK scheme. The present results at Ra = 5(10)10 are directly compared with those from the 1992 Workshop contributors.
