T1 - Single bubble ignition after shock wave impact T2 - The Micro-World Observed by Ultra High-Speed Cameras N2 - High-speed photography was applied to investigate the explosive behavior of bubble-containing systems of the type organic solvent---gaseous oxidizing agent. Knowledge about the explosive behavior of such systems is of great importance, for example, for the safe operation of chemical reactors in oxidation processes in the liquid phase. Examples of the complex dynamical reaction of bubbles are elucidated where bubble-containing liquids were subjected to the impact of shockwaves. The different stages of the shock-induced explosive behavior of oxygen and oxygen plus inert gas bubbles were studied experimentally and theoretically mainly in liquid cyclohexane. Other solvents, such as cumene and 2-ethylhexanal, have been found to show that shock-induced bubble explosions can occur even if the gas phase of the bubble is not in the explosive range before impact. Tue influence of different parameters on the bubble Explosion process, such as the composition of the bubbles and the initial pressure, was investigated. Limiting conditions for bubble explosions were determined. In addition to the behavior of individual bubbles, the interaction of exploding bubbles with one another was observed, which provides information on the Propagation mechanism of self-sustaining bubble-detonation waves. The results are important for the safety assessment of the explosion risks in corresponding two-phase systems.
