Experimental studies of explosion venting in a cylindrical vessel

摘要

Experiment investigations were carried out for the explosion venting in a 0.025m{sup}3 vertical cylindrical vessel. Mixtures of 4.1% propane air were used with central bottom spark ignition. When venting occurs at different failure pressure through different vent areas, pressure histories and flame propagating photos were obtained. Possible mechanisms responsible for vented explosion are discussed.
