Abstract
It is shown that detonation can be transmitted from a reacting bubble medium into an explosive gas volume located above the interface. Experiments were performed in which bubble detonation was initiated by wire explosion in a gas-liquid medium. The dynamics of the boundary of the gas-liquid medium after the arrival of the bubble detonation wave at it was studied. The distance between the wire and the boundary of the bubble medium was decreased to 1 cm, at which the gas volume was initiated by the hot products from the wire explosion and the discharge plasma. The probability of detonation transmission from the bubble medium to the volume of the gas mixture depending on the depth of immersion of the wire is determined, and the mechanisms of ignition of the explosive gas volume are described.
