Bubble Dynamics in N Dimensions [PDF]
Physics of Fluids, 2012 Cavitation and bubble dynamics are central concepts in engineering, the natural sciences, and the mathematics of fluid mechanics. Due to the nonlinear nature of their dynamics, the governing equations are not fully solvable.

Multi-bubble dynamics considering the direction of bubble–bubble interactions under acoustic field excitation [PDF]
Ultrasonics SonochemistryTo investigate the influence of bubble–bubble interactions on the vibrational dynamics of multi-bubble systems in cavitation fields, a multi-bubble dynamics model was established based on the Keller-Miksis equation.

Ultrasonics Sonochemistry, 1997 The dynamics of cavitation bubbles on water is investigated for bubbles produced optically and acoustically. Single bubble dynamics is studied with laser produced bubbles and high speed photography with framing rates up to 20.8 million frames per second. Examples for jet formation and shock wave emission are given.

Dynamics of Microbubbles Oscillating in Rheopectic Fluids Subject to Acoustic Pressure Field [PDF]
Journal of Applied Fluid Mechanics, 2023 In the present work, the dynamics of a single spherical gas bubble surrounded by a rheopectic fluid obeying the Quemada model is numerically investigated while the bubble undergoes oscillatory motion due to acoustic forcing.
