| 摘 要： | 本文用特片变量型的隐式ＮＮＤ格式计算了五种类型的高超声速激波－激波干扰流场，得到了清晰的流场结构图画。激波和剪切层等分辨得很清楚。计算的物面压力与实验甚为吻合。借助于激波极曲线，对第４类激波干扰结构进行了分析，解释了干扰引起物面压力增高的原因。

| Abstract: | n this paper,implicit NND scheme of characteristic form is used to calculate five types of viscous hypersonic shock-on-shock interferences,and the surface pressure agrees well with the experimental results.By using the pressure deflection diagram,the flow structure for type 4 shock wave interaction pattern is analysed,and we explains why the surface pressure is very high in this case. |
