Rozložení energie v kavitační bublině během jejího růstu a kolapsu
Müller, M. ; Maršík, František ; Garen, W.
Shock wave generation during the bubble growth and collapse and the corresponding energy separation were investigated experimentally. The calculation of the shock wave energy was based on the experimentally determined shock wave velocity profile. The possibility of using the similarity solution to determine the shock wave intensity is discussed. The velocity field around the collapsing bubble was visualized and compared with the numerical simulation using the commercial FLUENT code.
Spatial vapour density measurements inside laser induced cavitation bubbles
Hošek, Jan ; Garen, W. ; Shönig, H.
Cavitation bubbles have been studied and reported as an undesirable side effect in many of the medical application used of laser ablation like eye or cardio surgery in recent years. Our intention was to gain a physical information about processes inside the cavitation bubble. We develop a new technique for direct gas/vapour property measurements during the cavitation process in the bubble based on determination of bubble gas density.
