The usage of high speed impulse liquid jets for putting out gas blowouts

Abstract

The experimental examinations of gas flame suppression by a high speed impulse liquid jet generated by a powder impulse hydro-cannon have been carried out. The speed of the impulse jet depending on charge energy has ranged from 300 to 600m/s. The speed of the jet head right near the flame has been measured by a laser non-contact measuring device, the flow has been photographed. It has been shown that the high-speed cloud of splashes with a big cross-section around the jet is being formed. It effectively forces down the flame of the gas on distances 5-20m from installation.
