Observation of the Formation of Multiple Shock Waves at the Collapse of Cavitation Bubbles for Improvement of Energy Convergence

Autor: Marc Tinguely, Kiyonobu Ohtani, Mohamed Farhat, Takehiko Sato

Publikováno v: Energies, Vol 15, Iss 7, p 2305 (2022)

The collapse of a cavitation bubble is always associated with the radiation of intense shock waves, which are highly relevant in a variety of applications. To radiate a strong shock wave, it is necessary to converge energy at the collapse, and unders
