“…Han et al [27] numerically investigated the dynamics of two bubbles and observed that the annular jet causes bubble breakup and the axial jet formation. Peng et al [28] conducted numerical research on the interactions between two neighbored bubbles and analyzed the transition of strong interaction to the weak one. Li et al [29] studied the nonlinear interaction and coalescence characteristics of the oscillating bubble pairs by defining three different coalescing patterns.…”

“…The results show that the horizontally staggered bubbles are aligned due to the deformation caused by the interaction between the hydrodynamics and the bubbles, thus increasing the coalescence speed. Peng et al [19] used the modified single-component multiphase lattice Boltzmann method to simulate the weak interaction, strong interaction, and interaction between adjacent cavitation bubbles. It is found that under the interaction of two bubbles, the interaction changes from strong to weak with the increase of the initial distance of bubbles.…”

This paper investigates the bubble deformation in bubble growth using a self-made in-situ visual injection molding device. The results show that the deformation degree of independent bubbles is kept within 0.015. Under the frame rate of 25 frames per second (FPS), it is found that adjacent bubbles with the same average diameter simultaneously pass through the deformation critical point, while adjacent bubbles with different average diameters can't pass through the critical deformation point at the same time. The interaction in the process of adjacent bubble growth is simulated by finite element software, radial migration of bubbles is suppressed, the hoop stretch of bubbles is enhanced, and the deformation sequence of adjacent bubbles is determined by bubble radius and bubble pressure. On the basis of the bubble influence zone model and the bubble deformation model, a bubble deformation response model is established, used to reflect adjacent bubbles' deformation response speed.

“…Cavitation usually occurs when the pressure in a liquid stream drops below the local saturated vapor pressure, causing cavities to be generated at the internal or liquid-solid interface [1,2]. Cavitating flows are typically unsteady and exhibit phase changes, turbulence, and multi-scale vortices.…”

Cavitation involves complex multiphase turbulence and has important research significance. In this study, the Schnerr–Sauer cavitation model was used to model cavitation, and the detached-eddy simulation (DES) method was used to calculate the unsteady natural cavitating flow. The predicted results are in good agreement with experimentally measured cavity evolution and pressure values, demonstrating the effectiveness of this numerical method. Low temperature causes changes in the properties of water. The density of water at 0° is 999.84 kg/m3 and the density of water at 25° is 997.04. Cavitation evolution and shedding are analyzed at temperatures of 0 °C and 25 °C. The results showed that lower temperature increased the frequency of cavitation and enhanced pressure pulsation. At the same time, low temperature also increases the frequency of cavity shedding and shortens the cycle. In addition, based on the Ω method, the difference between vortex dynamics at various temperatures was studied, and it was found that different cavity stages showed different vortex structure characteristics, and lower temperature would aggravate the change of wake vortex structure. At the same time, the analysis of the turbulence characteristics in the downstream of the cavity shows that the lower temperature reduces the velocity pulsation and reduces the turbulence integral scale. At the end of the model, large-scale pulsations are transformed into small-scale pulsations.
