Acoustic Signatures of Pinch-Off Cavities During Water-Entry
Zirui Liu, Tongtong Ding, Mingyue Kuang +4
This study experimentally, numerically, and theoretically investigates the cavity/bubble dynamics and radiated acoustics during the water entry of a centimeter-scale cylindrical pr…
Supersonic jet dynamics from two-cavitation-bubble interactions: acceleration, tip fragmentation and penetration
Shuai Yan, A-Man Zhang, Tianyuan Zhang +3
This study experimentally and numerically investigates the dynamics of a high-speed liquid jet generated from the interaction of two tandem cavitation bubbles, termed bubble 1 and…
Influence of ambient temperature on cavitation bubble dynamics
Shaocong Pei, A-Man Zhang, Chang Liu +3
We investigate the influence of ambient temperature on the dynamics of spark-generated cavitation bubbles over a broad temperature range of 23 to 90. Increasing te…
New insights into the cavitation erosion by bubble collapse at moderate stand-off distances
Zhesheng Zhao, Shuai Li, Chengwang Xiong +3
Non-spherical bubble collapses near solid boundaries, generating water hammer pressures and shock waves, were recognized as key mechanisms for cavitation erosion. However, there is…
