用于激波控制反应器的原料气加速特性研究

Research on acceleration behavior of gaseous feedstock for a shock controlled reactor

为观察超声速混合过程,设计制造了专用的实验装置.实验结果表明:混合过程的总压损失随两种超声速流的密度比、静温比增大而增加.若密度比、静温比相同或相近时,速度差对总压损失的影响可忽略.但速度差随密度比、静温比增大而增大时总压损失亦随之增大.

The special experimental setup was constructed for observing the mixing processes of two supersonic flow. The experimental results show that the higher the static temperature and the density ratio between two supersonic flow, the more the total pressure losses of flow during mixing. The effect of the velocity difference on total pressure loss may be neglected, if the density and the static temperature difference are equal. But total pressure loss increases with the increasing of the velocity difference accompanied with the increase of the density and the static temperature ratio.
