Cavitation-bubble Interaction with an Initially Perturbed Free Surface
Jingyu Gu, Zirui Liu, A-Man Zhang +1
The interaction of a spark-generated cavitation bubble with an initially perturbed free surface is investigated experimentally, numerically, and analytically. By exploiting contact…
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…
A unified theory for bubble dynamics
A-Man Zhang, Shi-Min Li, Pu Cui +2
In this work, we established a novel theory for the dynamics of oscillating bubbles such as cavitation bubbles, underwater explosion bubbles, and air bubbles. For the first time, w…
A theoretical model for compressible bubble dynamics considering phase transition and migration
A-Man Zhang, Shi-Min Li, Run-Ze Xu +3
A novel theoretical model for bubble dynamics is established that simultaneously accounts for the liquid compressibility, phase transition, oscillation, migration, ambient flow fie…
