In order to investigate the influence of jet pressure on detonation initiation via imploding annular shock waves
detonation initiation with different jet pressures was simulated with hydrogen-air mixture.The results indicate that
when jet pressure is high enough
imploding annular shock waves can form high pressure and high temperature region that lead to direct initiation;thrust wall can strengthen reverberation shock
which contributes to initiate detonation;when the jet pressure is lower than its critical value
