Considering a fluid-fluid interface with a density jump provides a generalization of the already well-documented interactions of cavitation bubbles with rigid boundaries and free surfaces [27], [28], [32], [33], where a density ratio ρ1/ρ2→0 models the behavior of a bubble near a ...
Additionally, the interaction of cavitation bubbles near a free surface and inside a droplet has also been reported for an additional directional control of the jet formed during collapse20,21. In our previous investigation of employing neighboring cavitation bubbles, we showed the potential for ...
the LGI experiences a noticeable migration upwards with a slight deformation as the bubble approaches, due to the gas film initially forming higher than the nanoprotrusions (Supplementary Movie 2) and the absence of pinned contact lines, indeed resembling a free liquid surface (bottom two images ...

interaction). It is shown that a wide range of responsesmay be found with strong or weak bubble interactions, which clearly indicates the significant influence of the air bubble on the interaction between the cavitation bubble and a rigid boundary. ...
In order to examine this theoretical prediction, the behaviors of both a free bubble and a bubble adhered to the polymer were observed under ultrasound irradiation, using a high‐speed video camera. From the results, we found the reversal of the direction of the interactive force due to the ...
In this theory, the inner flow near the bubble is governed by the Laplace equation, while the outer flow is controlled by the linear wave equation. The dynamic boundary conditions at the bubble surface are corrected using a matching asymptotic expansion method. Specific algorithm details can be ...
The modeling of bubble dynamics near boundaries uses our general bubble dynamics and free surface modeling code, 3DynaFS©. Four modules are used in the study presented here and described below. 2.1. Boundary element model The potential flow model used in this study is based on a Boundary El...
