Abstract本文从高超声速流动中的层流流动模拟出发,分析了计算网格对气动力/热精确计算的影响。首先对25o/55oDouble cone 算例进行网格独立性分析,得到了得到了网格对流场结构的影响,然后对前台阶流动进行网格独立性分析,得到网格尺寸对前台阶流动的气动力/热的影响规律。结合其他算例的网格独立性分析,得到了高超声速流动精确计算所要求的网格独立性参数(网格雷诺数)的大小范围。另外并得到了网格放大比例的影响。通过反问题分析方法,人为的给定一个一维流场,通过分析,解释了计算网格如何影响高超声速流动气动力/热。同时也得到了网格放大比例的影响原因,在一定程度上提高了高超声速流动模拟的认识。
