| 摘要: |
| 有别于经典的量纲分析方法和对流动控制方程及其定解条件的无量纲化分析方法, 论文给出了一种分析流动相似律的新思路, 亦即将复杂的流动过程分解为若干个子过程, 然后分析每一个子过程中反映其本质性态的特征量。依据这一思路导出的高超声速热化学非平衡流动相似律与文献采用经典分析方法得到的流动相似律一致。 |

| Abstract: |
| Being different from classic dimension analysis method and dimensionless method of flow's governing equations and its certain resolving conditions, this paper presents a new method to analyze flow's similitude law, scilicet decomposing complicated flow process to some sub-processes and analyzing characteristic quantity which represents sub-process' essence nature. According to this new method this paper presents law of similitude in non-equilibrium thermo-chemistry hypersonic flows, which is consistent with the law of similitude obtained by classic method in reference. |
