摘要：

The theory of a two-equation turbulence model that satisfies the second law of thermodynamics is briefly reviewed. It is shown that the resulting governing equations resemble those of the k- epsilon model with the epsilon equation being different. The TEACH code is altered to account for the required modifications of the new model. Two test cases are considered in this study, a confined round jet expansion and a backward-facing plane step. The predicted velocity and turbulent kinetic energy profiles are compared with the experimental data and those obtained from the standard k- epsilon model.
