Abstract

In order to research the influence of the free supersonic jet pressure on jet collision, taking air as media, the experiment and numerical simulation of continuous supersonic jet collision in free space under different incident pressure were carried out. and the dynamic pressure and radiation noise of the jet collision center were analyzed. The results show that the dynamic pressure amplitude and the frequency of jet collision gradually increase as the injection pressure increases. At the same time the frequency of the noise caused by jet collision increases. The increase of the incident pressure can improve the effect of jet collision.

Key words： two-stage pulse detonation engine; free supersonic jet; incident pressure; collision; experiment and numerical simulation
