Numerical simulation of shock waveturbulent boundary layer interactions by solution of the NavierStokes equations
Abstract
Two turbulence models are evaluated for solving the NavierStokes equations (NSE) for flows with shock waveturbulent boundary layer (TBL) interactions. Of particular interest are interactions of varying intensity, with separated regions which increase in length. The models examined are a mixing length algebraic model and a dualtransport equation model. A multiple domains technique is employed to obtain solutions for the twodimensional flow in a channel. The NSE are used near the wall and the Euler equations in the freestream; solutions are calculated with an unsteady predictorcorrector explicit scheme and compared with laser velocimeter data for a twodimensional transonic flow in a test channel. The inadequacy of the mixing length model for predicting the length of the separated region is demonstrated. The capacity of the twoequation transport model, on the other hand, for describing the parietal pressure and the initial interaction is revealed; however, it fails to predict the downstream conditions.
