Explosion of a Bubble Curtain with a Combustible-Gas Mixture under the Action of a Pressure Pulse

摘要

A bubble liquid with a combustible gas (e.g., water with either detonating-gas bubbles or a hydrocarbon-oxygen mixture) is an explosive. In this liquid, a detonation soliton with an amplitude of up to hundreds of atmospheres can arise under the action of a pressure pulse on the order of 10-20 atm. The specific mass caloricity of such an explosive is lower by six or more orders of magnitude than for usual solid, liquid, and gaseous explosives. These low-caloric explosives are efficient means of amplifying and maintaining was signals, as well as of temporarily elevating the pressure in local zones. In addition, in combustible liquids containing curtains with vapor-air bubbles, sharp shocks arising in the process of transportation can promote formation of detonation solitons leading to emergencies.
