关 键 词：flame front propagation characteristics combustible mixture bend shape initial concentration flame arresters
摘 要：正The analysis on characteristics of flame front of propane-oxygen-air mixtures propagating in channels were carried ***,the influences of the initial concentration and the bend shape of the combustible mixtures on the flame velocity were studied by *** experimental results indicated that the flame velocity propagating through the bend increases as the mass percentage of propane ranges from 5.84%to 6.24%.It increases more than 20%for experimental setup A for the given analytical *** existence of bend in channels plays an important role on the flame front acceleration of combustible *** comparing the different bend shapes,the increment rate of velocity of flame front exists distinct obviously and the experimental setup B is the most valid than others to prohibit the flame acceleration in the *** the experimental results could provide reference for safety use of flame arresters in industry.
