采用Ｈａｒｔｅｎ－Ｙｅｅ的二阶精度隐式ＴＶＤ格式对Ｎ－Ｓ方程进行数值模拟，研究了后掠角为６５°和７０°的三角翼绕流的流场特性。计算结果表明：ＴＶＤ格式中限制器函数的选取对于三角翼绕流结构的计算结果具有较重要的影响。结合张涵信的旋涡定性分析理论对旋涡的发展过程进行研究，此外，还对二次涡破裂现象和网格分布影响等问题进行了探讨。
The second order implicit TVD scheme of Harten-Yee is used to simulate the N-S equation. The flow fields around the delta wing with the sweep angles of 65 ° and 70 ° are studied. The calculation results show that the selection of the limiter function in the TVD format has a more important influence on the calculation results of the delta wing flow structure. Based on the theory of vortex analysis by Zhang Huanxin, the development of vortex is studied. In addition, the problems of secondary vortex rupture and the influence of grid distribution are also discussed.
