Application of an Unstructured Grid Flow Solver to Compressible Turbulent Flows

A numerical method for the prediction of turbulent compressible flows around complex configurations, which has been previously developed and validated [1], [2], has been employed for the computation of turbulent compressible flows of aeronautical interest. In order to allow a proper description of complex flow features, such as those resulting from shock-wave/boundary layer interactions, advanced turbulence models have been employed. Eddy-viscosity two-equation models as well as second-moment closure turbulence models have been adopted for this purpose. The results obtained for transonic flows around two-dimensional airfoils show that the usage of more sophisticated turbulence models such as the ’basic’ Reynolds stress model can enhance the prediction capabilities.
