Modeling of combustion-to-detonation transition in a cylindrical bubble with non-smooth boundary

详细

The paper describes experimental modeling of combustion of a stoichiometric propane-oxygen mixture in quasi-cylindrical bubbles with non-smooth interface using polyvinyl chloride tubes with barriers inside (multiple or single water droplets; or the balls of polystyrene and steel). The transition from combustion to detonation occurs both before and after the barrier, for any kind of barrier material.
