摘要: Abstract Explosion always occur in turbulent ambience, but few researches focusing on the effects of turbulence explosion characteristics has been performed current. In present investigation, initial stoichiometric and rich hydrogen-air mixtures were experimentally studied analyzed basis pressure traces. Maximum pressure, duration, maximum rate rise, fast deflagration index, averaged heat flux through wall during systematically examined. The results indicated that, will reduced corresponding equivalence ratio to rise won’t change ratios two durations. durations decline for accelerated propagation wave, values be raised vessel’s explosion. addition, raises value namely it hazardous level.
