[en] Discontinuous Galerkin ; interior penalty ; Reynolds-averaged Navier-Stokes
[en] A 3D high-order RANS solver in conservative variables has been developed, based on a discontinuous
Galerkin/Symmetric Interior Penalty discretisation. The turbulence model is the well-known one-equation Spalart-Allmaras model. It is shown that in order to stabilise the discretization scheme, it is necessary to adapt the transpose penalty term, which introduces an explicit dependency of the continuity equation on the turbulent viscosity.
