Abstract
High speed photography techniques have been used to study the sensitising effects of air bubbles volume a few mm 3) within thin films of spark-ignited nitroglycerine. The collapse of the bubble is shown to lead to an increase in sensitivity of the liquid explosive, by (a) locally increasing the deflagration velocity and (b) generating a pressure pulse which is capable of producing hot spots at cavitation sites within the liquid. If several gas bubbles are included, cooperative effects are observed which lead to increased sensitiveness. The results support a distributed hot spot model for low velocity detonation.
