| 摘要: |
| 基于RANS方程，采用有限体积法离散计算区域，对流项使用Harten TVD格式进行流场求解，湍流部分应用Menter SST两方程湍流模型，建立了隐式LU-SGS方法的三维CFD计算程序，数值模拟了来流马赫数4.96条件下的18°×18°对称双楔产生的交叉激波/湍流边界层干扰问题，计算了不同剖面沿展向压强分布以及流场的详细结构，并将计算结果与相关文献的实验与计算结果进行了比较。 |

| Abstract: |
| A 3d LU-SGS computational code was developed to solve the hypersonic flows, which was modeled by using the compressible three-dimension Reynold averaged Navier-Stokes equations and a finite volume formulation, the convective parts were discretized with the Harten TVD scheme, and the turbulence effect was modeled utilizing Menter SST two equation turbulence model. The flowfield of 18×18 degree fins generated crossing shock wave/turbulent boundary layer interactions were studied at Mach 4.96, a 3D separated flowfield was analyzed and the numerical results were compared with experimental and numerical results from references. |
