Non Linear Κ-ε Turbulence Modeling for Industrial Applications

The non linear eddy viscosity models are good candidates for the simulation of turbulent flows of industrial interest. In fact these models allow to avoid the complexity of the second-order closure models, and to capture more physics than the classical two equation turbulence models based on the Boussinesq hypothesis. Non linear κ-ε turbulence models have been developed by the authors, in the framework of the CEC BRITEEURAM project AVTAC, and so far validated in case of a transonic flow around an airfoil and a wing mounted in a wind tunnel. The aim of this paper is to assess the behaviour of the developed non linear turbulence models in case of a typical complex 3-D aeronautical application such as the flow around a wing-body configuration.
