Title:
Amplification of supersonic micro-jets by resonant inertial cavitation-bubble pair
Abstract:
We reveal for the first time by experiments that within a narrow parameter regime, two cavitation bubbles with identical energy generated in anti-phase develop a supersonic jet. High-resolution numerical simulation shows a mechanism for jet amplification based on toroidal shock wave and bubble necking interaction. The micro-jet reaches velocities in excess of 1000 m s−1. We demonstrate that potential flow approximation established for Worthington jets accurately predicts the evolution of the bub...     »
