在ＴＶＤ格式的基础上，以修正限制函数的方法，将通常的ＴＶＤ格式改造为性能更为优越的ＥＮＯ格式，并利用这种有限差分格式求解欧拉方程和薄层Ｎ－Ｓ方程。分别数值模拟了激波管中运动激波与三种楔形物体相互作用流场；给出了激波在不同物体上的反射及波涡干扰过程中非定常流场的变化情况；算出的波系结构与在ＣＡＲＤＣ小型激波管中做的相关实验结果一致。
Based on the TVD format, the normal TVD format is modified to a more superior ENO format by modifying the limit function, and the Euler equation and the thin layer N-S equation are solved by using this finite difference scheme. The interaction between the shock wave and the three wedge-shaped objects in the shock tube is numerically simulated. The variation of the unsteady flow field during the reflection of the shock wave and the disturbance of the wave vortex is given. The structure is consistent with the relevant experimental results in CARDC mini-shock tubes.
