第 45 卷 刘 江，等： 有限长锥体诱导的斜爆轰波非定常结构的数值研究 第 9 期

论对爆轰波阵面的不同结构进行了讨论，得到如下结论。
(1) 具有轴对称结构的有限长尖锥，爆轰波后流场受到 Taylor-Maccoll 流动和 Prandtl-Meyer 膨胀波
的影响，其流动处于非均匀状态。
(2) 激波与化学反应的非线性耦合和波后的非均匀流场对爆轰波结构产生较大的影响，使其呈现
4 种不同的结构：光滑的类 ZND 结构、单三波点的类胞格结构、双三波点的胞格结构和 Prandtl-Meyer 影
响的非规则双三波点结构。
(3) 根据爆轰波阵面三波点的轨迹绘制的爆轰胞格结构，呈现与其结构对应的特征：光滑平面结构、
平行直线结构、斜菱形结构和不规则的斜菱形结构。与此同时，在爆轰波的双三波点结构中，面向上游
传播的爆轰波更强。
