| 摘 要： | 采用A.Harten的高分辨率总交差不增(TVD)格式,对激波反射问题和带有台阶的二维风洞中高超声速绕流问题进行了数值模拟。计算结果表明:TVD格式比传统的数值格式如Godunov,BBC,Muscl,及PPM等有较高的激波分辨率,且伪振荡小。

| Abstract: | In this paper,high resolution for shock waves,second order ac-curate TVD schemes proposed by A. Harten have been used to numericallysimulate the problem of shockwave reflection and the hypersonic diffraction intwo dimensional wind tunnel with step. The computational results have indi-cated that TVD schemes can produce higher shock resolution and little spuriousoscillation than the classical shock capturing methods such as Godunov, BBC,Muscl, PPM schemes. |
