Keywords: turbulence modeling, reynolds tensor, constitutive relation
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 ?-e
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.
