APPLICABILITY OF THE STANDARD K-EPSILON TURBULENCE MODEL TO GAS-STIRRED BATHS

Recently, Mazumdar and Guthrie found that they were unable to simulate the flow fields in a model steel processing ladle using the standard kappa - epsilon turbulence model. They made adjustments to the empirical constants in order to obtain agreement between the predicted and experimental velocities. In this paper a more sophisticated two-phase model that solves for void fraction and both phase velocities is used. This method in conjunction with the standard kappa - epsilon model yields flow fields in good agreement with the data published by Mazumdar and Guthrie.
