Special attention must be paid to the turbulence modeling in order to enhance the reliability of the computational approaches. In this study, three turbulence models are assessed for separated flows involving shock-wave/boundary-layer interactions. The models investigated consist of the algebraic model of Baldwin-Lomax, the one-equation model of Johnson-King and the two-equation model of Coakley. A comparison of computed and measured results indicates that the Johnson-King model has the best performance and that non-equilibrium types of turbulence models are essential for accurate prediction in transonic separated flow analysis., 資料番号: NALSP0010008, レポート番号: NAL SP-10}, title = {圧縮性流れ解析における乱流モデルの検討}, year = {1989} }
