摘要
针对典型高超声速流动问题(T2-97模型),利用Richardson插值法,研究了多套连续变化网格下数值解的空间离散误差、收敛性。通过网格收敛性研究,完成了CFD的验证过程。利用不确定度分析方法,结合实验数据,开展了该问题的确认。研究表明:针对所选问题,在现有实验数据及计算条件下,该问题的CFD得到了验证与确认。
In this paper, the discretization error and the convergency are studied for the typical hypersonic flow over hollow cylinder flare（T2-97） using a several successive girds, and a verification procedures based on the Richardson Extrapolation are carried out for this problem. Then with the uncertainty analysis method and the experiment data, the validation procedures are also carried out. The study indicates that the typical problem＇s Verification and Validation work is achieved based on the existing experiment data and computa- tional capability.
