增设收缩截面后的爆轰驱动激波管性能研究

摘要

In order to increase the performance of the detonation driven shock tunnel, some converging throats are added in driver section near the main diaphragm.Experimental results indicate that this way can availably weaken the effect of Taylor rarefaction waves.%为提高前向爆轰驱动激波风洞的性能，采用在驱动段靠近主膜处增设一个收缩喉道的方法，以此来产生较为均匀的驱动气源。实验结果表明此方法有效地削弱了爆轰波后Taylor稀疏波的影响。
