Shock cavitation
Web16 Jul 2024 · In this study, the shock wave transmitted inside the bubble and the water-hammer shock formed in the liquid are under quantitative investigation. Numerical results reveal that the interactions between the shock wave and bubble interface give rise to peak pressures of liquid phase, and the initial stand-off distances have important influence on … Web5 Jan 2024 · 2.1 Experimental Setup. Figure 1 shows the experimental setup of the water-jet cavitation shock microbulging process. The experiments were performed in a transparent water tank filled with tap water at 25±2 °C. According to Refs. [16,17,18], the cavitation nozzle with a d/L ratio of 1:8, as shown in Figure 2, was designed to generate a periodic …
