This paper shows that accurate predictions of skin friction coefficient and Stanton number can be achieved with the k - epsilon model of turbulence with wall functions. Success hinges on the judicious use of the model. Turbulent flow and heat transfer over a flat plate are used as test cases....
Two equation turbulence models are one of the most common types of turbulence models. Models like thek-epsilon modeland thek-omega modelhave become industry standard models and are commonly used for most types of engineering problems. Two equation turbulence models are also very much still an activ...
Models for Engineering Applications F. R. Menter* NASA Ames Research Center, Moffett Field, California 94035 Two new two-equation eddy-viscosity turbulence models will be presented. They combine different elements of existing models that areconsidered superior totheir alternatives. The first model, ref...
31 GEKO Turbulence Modeling in Ansys CFD / 2 1. Motivation Two-equation turbulence models have matured to a point where a consolidation seems desirable. The main models used in industrial CFD codes today are k- [14] (standard and realizable/RKE), k- ...
Three linear two-equation turbulence models k 蔚, k 蠅 and k 1 and a non-linear k 1 model are used for aerodynamic and thermal turbine flow prediction. The pressure profile in the wake and the heat transfer coefficient on the blade are compared with experimental data. Good agreement is ...

A two‐equation turbulence model has been developed for predicting two‐phase flows. The two equations describe the conservation of turbulence kinetic energy and dissipation rate of that energy for the carrier fluid in a two‐phase flow. They have been derived rigorously from the momentum equations...
