Abstract
The shock wave focusing is a promising detonation initiation method that can greatly shorten the deflagration to detonation transition distance. In this work, we conducted experiments under the constant operating pressure in a conical reflector to explore the shock focusing induced ignition in CH4/O2/Ar mixture. The second ignition is formed in the conical reflector under certain conditions. The introduction of the second ignition brings a higher pressure peak after ignition. By adjusting the incident shock intensity, three modes of ignition are found in the conical reflex. The pressure peak of combustion and the time to induce the second ignition are systematically investigated.
