反射激波作用下三维凹气柱界面演化的数值研究1) 崔竹轩, 丁举春, 司廷 NUMERICAL STUDY ON THE EVOLUTION OF THREE-DIMENSIONAL CONCAVE CYLINDRICAL INTERFACE ACCELERATED BY REFLECTED SHOCK1) Cui Zhuxuan, Ding Juchun, Si Ting 图9 不同反射距离 (40 mm, 80 mm, 120 mm) 下3个典型截面上的界面演化过程. 每个图的上半部分为涡量图, 下半部分为纹影图, 单位为$\mu$s.为便于观察, S3截面图放大至S1 (或S2)截面图的1.5倍(界面和激波位置看着略有不同) Fig.9 Evolution process of concave light gas cylinder under reshock along three typical cross section (time unit: $\mu$s). The plotting scale of the S3 cross section is 1.5 times larger than other frames in order to be observed clearly, thus the scale and the relative location of the deformed interface and shock waves shown in these frames seem different
