Turbulence Model Evaluation in Circular Pipe of Supercritical Water Based on Statistical Method

Up to now, the traditional turbulence model evaluation in supercritical water still has some uncertainties to some degree. The basic reason is the limit of model itself which makes the model depend on the calculation parameters. This paper focuses on the turbulence model evaluation based on the batch process techniques of CFD tools through comparing with the experimental data base. Some typical turbulence models were analyzed against the experiments. The performance of each model was evaluated based on the statistical method. The dependencies of the performance on operation conditions were discussed.
