Improvement of Corner Flow Prediction Using the Quadratic Constitutive Relation

摘要: This paper presents results of the implementation Spalart’s quadratic constitutive relation into Reynolds-averaged Navier–Stokes equations on two applications encountered in applied aerodynamics. These applications, one external flow and internal flow, are intended to be representative problem corner simulation, with separation size being generally overestimated by classical turbulence models. The first application is DLR-F6 wing/body configuration used Drag Prediction Workshop, where a occurs at junction case without fairing. second shock-induced rectangular duct. It shown that greatly improves accuracy simulation worsening quality solution elsewhere.
