On conditions enabling resonant combustion in gas explosion in non-enclosed volume

Abstract
It has been observed, that resonant combustion may develop in gas explosions taking place in chambers with light relief panel after the panel is removed. It has been noted, that initiation of the resonant combustion coincides with the moment of the combustion wave approaching the chamber walls. It has been found out that the location of the ignition point has a great influence over the oscillation intensity: when the ignition happens closer to the center of the chamber, the amplitude increases and may reach the values that are from 5 to 10 times higher than the panel removal pressure, thus signifying the resonant combustion as a highly hazardous factor.
