摘要
Abstract
High-speed photography was used to test the combustion frame propagating process of the equivalent concentration mixed methane-air gas in the cylindrical Poly(methyl methacrylate) (PMMA) tube. The accurate mathematical model was established, and a test system was built. The video images collected by a high speed CMOS camera were processed and calculated by Matlab, and the flame front propagating velocity curve was drawn, which can reappear the combustion process of mixed methane-air gas clearly. It found that the acceleration and deceleration cycle of the equivalent concentration mixed methane-air gas flame front is about 2.5ms--3.5ms, after analyzing the flame front propagating speed curve. The research findings have an important reference value to the control and investigation of the mash gas accident.关键词
