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。
Aiming at the typical hypersonic flow (T2-97 model), Richardson interpolation is used to study the spatial discretization error and convergence of numerical solutions of several continuous changing meshes. Through the research of grid convergence, the CFD verification process is completed. Uncertainty analysis method, combined with experimental data to carry out the confirmation of the problem. The research shows that under the existing experimental data and calculation conditions, the CFD of this problem has been verified and confirmed for the selected problem.
