In this work, we use a stabilized finite element method to solve Spalart-Allmaras turbulent model for compressible flows. This method is the Streamline-Upwind Petrov-Galerkin one, which enable to put numerical viscosity only along the streamlines. The aim is to build a high order scheme in order not to pollute turbulent eddy viscosity with the...

When high Reynolds turbulent flows are combined with complex and large size geometries, computers are no longer enough powerful to deal with Direct Numerical Simulation (DNS) and with the resolution of all the scales of turbulence motion. Therefore, the RANS approaches solve averaged equations and use a model to simulate these scales. This...

When high Reynolds turbulent flows are combined with complex and large size geometries, computers are no longer enough powerful to deal with Direct Numerical Simulation (DNS) and with the resolution of all the scales of turbulence motion. Therefore, at a fixed scale suitable for reasonable computations cost, the unresolved scales of the...

The majority of fluid flows that are interesting from a practical point of view are turbulent flows. The problem is that turbulence is particulary difficult to model. Although simulation of turbulent flows has been the topic of important researches, it remains an open issue. We present a stabilized finite element method combine with the one...
