Introduction

Shock wave/boundary-layer interaction (SWBLI) is a common but important flow phenomenon, within various engineering design areas such as engine inlets, compressors and turbines. In past decades, researchers have made great efforts towards better understanding and modeling of SWBLI flows. The reviews by Knight and Degrez[1], Zheltovodov[2], Dolling[3] examine the capability of Reynoldsaveraged Navier-Stokes (RANS) turbulence models in the prediction of SWBLI. The common conclusion is that most RANS models based on the linear formulation of the Boussinesq assumption are difficult to accurately predict details of flow separation, i.e. the distributions of pressure loads, heat transfer and skin friction. In consequence, a lot of efforts are put in deriving non-linear RANS turbulence models, either in an explicit algebraic form or through transport equations for the Reynolds stress components. The ongoing research emphasis is to get a physically reliable understanding of SWBLI and to reach a point where a unique non-linear formulation could be used for the modeling of Reynolds stress in a large range of flow configurations.
