| 摘 要： | 用不同的数值格式，包括Ｒｏｅ的ＦＤＳ格式和ｖａｎＬｅｅｒ的ＦＶＳ格式并配备不同限制器，求解二维Ｎ－Ｓ方程，模拟研究了激波／边界层干扰的流动问题，分析了模拟出的流动现象，仔细研究了其中的格式效应，得出同前人不尽一致的结论：ｖａｎＬｅｅｒ格式对限制器的依赖性比Ｒｏｅ格式更强；在本文情况下，ｍｉｎｍｏｄｌｉｍｉｔｅｒ的激波、膨胀波的分辨率比ａｌｂａｄａｌｉｍｉｔｅｒ还好

| Abstract: | Shock/boundary layer interaction is simulated by solving 2 dimensional N S equations using different numerical schemes, including Roe's FDS scheme and van Leer's FVS scheme fitted with different limiters. The computed flow phenomenon is analyzed and a study on the varying scheme effects is made.Some new opinion is presented. |

| Keywords: | shock boundary/layer interaction numerical solutions resolution |
