Reducing the critical pressure of detonation initiation in transmission to a semiconfined volume

The classical methods of initiating detonation in a volume of a reacting mixture have been studied in sufficient detail but they are not always suitable for practical purposes. This paper studies the effect of different stages of the deflagration-to-detonation transition in a small-diameter tube on the efficiency of initiation of gaseous detonation in transmission to a semiconfined volume. The methods of initiation described in this paper are important for assessing the risk of fire and explosion in household use and especially in industries.
