N2 - Previous tests at a test bench in Iampoldshausen revealed a phenomenon in which the first peak of the pressure surge was not the highest one Instead the second peak exceeds the first peak by more than 25%. Other tests showed pressure spikes in the cavitation area In an attempt to explain both phenomena, a high speed imaging setup was installed at the test bench The resulting images will be presented in this paper, together with the bubble position over time The experiments indicate, that the second phenomenon is related to the flow reversal prior to column reintegration of the cavitating liquid column.
