The shock induced explosion behavior of oxygen bubbles in cyclohexane under normal conditions has been investigated. For the investigations a cylindrical autoclave containing a bubble generator was used. High speed optical and pressure measurements were carried out. In the present work the explosion behavior of bubbles was investigated not only in the first pulsations after the icident shock wave passage, as is the general practice in the literature, but also for many pulsations after it. Two types of bubble ignition were observed. One type of explosion is the well known bubble explosion occuring in the first bubble pulsation after the shock wave impact. The other type was previously unknown. It takes place after many bubble pulsations and has a significantly longer ignition delay. The behavior of a single bubble, which showed the second type of ignition is described. Furthermore it is shown by optical measurements that both types of bubble ignition can take place under the same conditions, i.e. during the same experiment.
