中文摘要 | 本文旨在探討各類紊流模式在斜震波/邊界層相互作用流場的應用效 果,鑑於此流場的現象十分複雜,故擬解Reynolds-Averaged Navier-Stoke方程式。 所使用的數值方法為顯式多階上風通量差分法(Explicit Multi-Stage,High-Resolution Upwind Flux-Difference Split Scheme,Roe's Schemed,配合不同的紊流模 式:Baldwin-Lomax的代數模式,Mitcheltree單方程式模式及Launder-Sharma K-ε雙 方程式模式。並將計算結果與實驗數值相互比較,以得到在此流場中最適合與 Roe's Scheme合用之紊流模式,計算結果顯示以Mitcheltree單方程式模式最為準 確。 |
英文摘要 | This paper describes the application of different turbulence models to the shockwave/boundary layer interaction porblem. Such a problem will be studied by solving theReynolds-averaged Navier-Stokes equations since its flow field phenomena is very complex.The numerical method used is the explicit multi-stage, high-resolution upwind flux-differencesplit scheme ( Roe's scheme ) coupled with different turbulence models including Baldwin-Lomax algebraic model, Mitcheltree one-equation model, and Launder-Sharma k-εtwo-equation model. We also compare the results with experimental data, the agreement is generally good. Of all the different turbulence models, one equation is more compatible than others. |
