Abstract

Abstract

To obtain more accurate images of the shock wave formation process, pressure and flame propagation velocity, and flow field evolution of flame-inert flame retarding interaction duringpremixed gas/air deflagration in a blast shock tube, by analyzing the time response’s characteristics and the control modes of multiple targets in the shock tube test system, we designed two experimental schemes using an ultrahigh speed camera, a photomultiplier tube, a time delayer, a solid state relay, a charge amplifier and a data acquisition system, and tested the response time of the high pressure ignition system and the inert medium flame retarding injection system. The results showed that the response time of the spark ignition is microsecond, and that of the flame retarding injection system is millisecond. Based on the response time, we realized the multi-objective synchronous control by setting a precise delay time, thus laying a foundation for the display of a micro-flow field of premixed gas/air deflagration in a shock tube.
