Numerical simulation based on CE/SE method for airfoil flow with shock wave

  • 摘要: 在二维四边形结构网格下,针对时空守恒元和解元(CE/SE, space-time Conservation Element and Solution Element)方法捕捉激波需要双倍空间网格点的问题,重新对守恒元和解元进行了定义,计算点同时包含单元中心和网格节点,并推导得到了新的CE/SE方法的计算公式.以此为基础,结合非敏感克朗数(CNIS, Courant Number Insensitive Scheme)计算格式和当地时间步长方法,对激波翼型流场进行数值模拟,并与原方法及AGARD报告进行对比.结果表明,对原CE/SE方法的改进是有效的,可明显提高激波分辨能力,并且激波前后无明显的数值震荡发生,新方法适合应用于翼型流场中捕捉激波.
