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。
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.
