1-방정식 모형을 이용한 충격파-난류 경계층 상호작용 유동의 해석

Abstract

The performance of one-equation turbulence models of Baldwin-Barth and Spalart-Allmaras is assessed against shock-turbulent boundary layer interaction flow. The flow configurations are the 20 degree compression ramp flow and the axisymmetric bump flow. The Baldwin-Lomax, Baldwin-Barth, and Spalart-Allmaras models have been implemented into the compressible Navier-Stokdes code. Modification of the Baldwin-Barth model for non-equilibrium turbulence flow is suggested. Computational results indicate that the model modification yielded substantially improved solution.
