The synchronized force impact measurement and visualization of single cavitation bubble generated with LIB

Original language description

In this paper we present the results of the synchronized investigation of the single cavitation bubble behavior. The cavitation bubble is generated with Laser Induced Breakdown (LIB) technique that is based on single laser shot that is synchronized withc high speed shadowgraphy visualization and the pressure force measurement. The bubble dynamics response in the field of fluid can be detected acoustically by PVDF needle hydrophones or optically by high speed CCD cameras working on frequencies up to 180kHz. Here we present two PVDF film signals corresponding to two bubble wall distances and we are following the run of the first peak in the signal, which corresponds to the interaction between the wall and shock wave, which is radiated at the bubble initiation due to rapid plasma expansion. The main goal of this research was to set the optical setup for the laser induced breakdown and to create the calibration relation curve for the bubble size dependence on the input energy of the lase
