A weakening reflected shock wave method in oscillating tube;
一种削弱振荡管内反射激波能量的方法
The results indicated that the overpressure of reflected shock wave was much stronger,which was about 2 times higher than that of incoming shock wave.
结果表明反射激波超压明显增强,约为入射激波超压的3 倍,并可引起动物肺和胃肠道损伤;绕射激波的一次激波超压明显降低,约为入射激波的1/3 ,二次激波与距挡板的距离有关,当距离为挡板高度的1/4 和2 倍时,超压低于入射激波,距离为挡板高度的1/2 和1 倍时,超压稍高于入射激波,提示该处激波有叠加现象,实验动物均未见明显内脏器官损伤。
