Applicability of the standard k-ϵ turbulence model to gas-stirred baths

Abstract Recently, Mazumdar and Guthrie found that they were unable to simulate the flow fields in a model steel processing ladle using the standard k -ϵ 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 k -ϵ model yields flow fields in good agreement with the data published by Mazumdar and Guthrie.
