Abstract:
In order to be able to “see” the information inside the structure about premixed gas of air and gas deflagration flow field in a underground coal mine, to recognize the coupling relationship between shock wave and flame, obstacles accelerating the incentive effects of the flame, the nature of the inert medium flame retardants to suppress deflagration, the super high-speed laser schlieren system was further built on the existing mesoscale explosion shock wave pipeline, and the experimental test scheme of “M”, “Z” and linear optical path arrangement was proposed to replace the traditional pressure flame sensor test method, it provides a new idea to obtain the evolution process of shock wave and the microstructure flow field of flame when gas/air premixed gas is deflagrated.
