Résumé :
|
Numerical predictions were carried out for turbulent natural convection in two tall air cavities. The standard and RNG k- turbulence models were used for the predictions. The predicted results were compared with experimental data from the literature. Improved prediction was achieved using the RNG k- model in comparison with the standard k- model. The principal parameters for the improvement were investigated.
