“…The bubble may split into two daughter bubbles with two jets impacting on both walls when the gap is sufficiently small and the bubble is nucleated near the gap centre (Chahine 1982;Kucherenko & Shamko 1986;Ishida et al 2001;Azam et al 2013;Ogasawara et al 2015). This behaviour has been reproduced by simulations using the boundary element method (Zhang et al 2010) and volume of fluid (VoF) method with a finite volume method framework (Han et al 2018). For a bubble created very close to one wall in a gap with a height comparable to the bubble's maximum radius, it may translate to and induce a jet impacting on the distant wall during collapse.…”

According to the behaviors of a bubble in the ship wake flow, the numerical simulation is divided into two stages, quasi-spherical motion and non-spherical motion, based on whether the bubble is captured by the vortex or not. The one-way coupled particle tracking method (PTM) and the boundary element method (BEM) are adopted to simulate these two stages, respectively. Meanwhile, the initial condition of the second stage is taken as the output of the first one, and the entire simulation is connected and completed. Based on the numerical results and the published experimental data, the cavitation inception is studied, and the wake bubble is tracked. Besides, the split of the bubble captured by the vortex and the following sub-bubbles are simulated, including motion, deformation, and collapse. The results provide some insights into the control on wake bubbles and optimization of the wake flow.

“…On the other hand, BBI have been extensively studied in various flow fields, such as in infinite flow field, 22,23 near the walls, [24][25][26] in homogeneous bubbly flows, 27 in a sound field [28][29][30][31] and under given pressure waves. 32 It is found that the coupling of bubbles may lead to a variety of phenomena that a single bubble can never exhibit, such as attraction and repulsion of pulsating bubbles, 24,28,33,34 phase delays 35 and even coalescence.…”

Bubble-bubble interactions play important roles in the dynamic behaviours of multiple bubbles or bubble clouds in a vortical flow field. Based on the Rayleigh-Plesset equation and the modified Maxey-Riley equation of a single bubble, bubble-bubble interaction terms are derived and introduced for multiple bubbles. Thus, both the Rayleigh-Plesset and modified Maxey-Riley equations are improved by considering bubble-bubble interactions and then applied for the multiple bubbles entrainment into a stationary Gaussian vortex. Runge-Kutta fourth-order scheme is adopted to solve the coupled dynamic and kinematic equations and the convergence study has been conducted. Numerical result has also been compared and validated with the published experimental data. On this basis, the oscillation, trajectory and effects of different parameters of double-bubble and multi-bubble entrainment into Gaussian vortex have been studied and the results have been compared with those of the cases without bubble-bubble interactions. It indicates that bubble-bubble interactions influence the amplitudes and periods of bubble oscillations severely, but have small effects on bubble trajectories.
