LES of direct detonation induced by incident circular shock wave focusing

  • Based on large eddy simulation(LES), an element reaction model was used to investigate direct detonation induced by incident circular shock wave focusing of hydrogen-air combustible mixture by detailed numerical simulation. Research results show that, under the condition of inlet Mach number of 2.5, the high energy region by incident circular shock wave focusing may achieve direct detonation for detonation wave formation in combustible gas, and fuels can react efficiently and completely. Vertical circular shock wave can't induce the process of detonation. So, incident circular injection is more useful to direct detonation by fuel mixture focusing.
