Laser generated plasma followed by shocks and increasing cavitation bubble in a mini-glass tube
- There have been tried many types of micro-capillaries, square or round and with different sizes of inner diameter. In which a cavitation bubble was created. The purpose of these experiments was to observe the velocity of the shock wave just after the initial cavitation bubble the rebound ones inside the micro-capillary and outside the micro-capillary. The most of the method was spark to induced superheat limit of liquid. Here we used the laser-induced breakdown (LIB) method. There were described the set cavitation setting that affects the stability and size of the bubble. We used here shadowgraphy setup for visualized the cavitation bubbles and shock wave with a camera. There were observed time development of the shock wave velocity; the velocity of the initial shock wave inside the micro-capillary was higher than the shock velocity outside the micro-capillary
