“…(7) and (8). The smoothing scheme [12] and EMT technique [14] are employed to tackle the problems of numerical instabilities and severe mesh distortion, which may occur due to the iteration procedure and jet impact. The time step for each of iteration procedure has to be chosen carefully with the criterion as below…”

“…However, the abovementioned work was in the scope of two-dimensional bubble simulation. In recent years, Wilkerson [8], Chahine [9], Harris [10,11], Zhang [12,13] and Wang [14] proposed basic numerical methods and developed computer codes to simulate three-dimensional bubble dynamics. Klaseboer and Khoo [15,16] made three dimensional simulations of the underwater explosion bubble using boundary element method, and successfully obtained dynamic behaviors of underwater explosion bubble near a rigid and resilient structure.…”

The basic principle and numerical technique for simulating two three-dimensional bubbles near a free surface are studied in detail by using boundary element method. The singularities of influence coefficient matrix are eliminated using coordinate transformation and so-called 4π rule. The solid angle for the open surface is treated in direct method based on its definition. Several kinds of configurations for the bubbles and free surface have been investigated. The pressure contours during the evolution of bubbles are obtained in our model and can better illuminate the mechanism underlying the motions of bubbles and free surface. The bubble dynamics and their interactions have close relation with the standoff distances, buoyancy parameters and initial sizes of bubbles. Completely different bubble shapes, free surface motions, jetting patterns and pressure distributions under different parameters can be observed in our model, as demonstrated in our calculation results.

“…Finally, the bubble surface is remeshed or smoothed using the elastic mesh technique [47], local five-point smoothing scheme [28], or linear interpolation. Our results indicate that the linear interpolation regridding method outperforms the other two methods for axisymmetric problems.…”

An understanding of biotissue-bubble interactions and the stresses induced in the tissue is needed to identify potential mechanisms of tissue damage, such as vessel rupture, by acoustically excited bubbles. Interactions between acoustically excited bubbles and nearby rigid structures have been studied effectively using the boundary element method. However, if the nearby structure is a biotissue, structure deformations will affect the bubble response. In this paper a coupled finite element and boundary element code, developed to investigate the interactions between an acoustically excited bubble and a deformable structure, is presented. In particular, this model was developed to investigate the response of bubbles within deformable tubes. This code is validated by comparison to other simulation and experimental results and employed to obtain the response of an acoustically excited bubble centered within a tube. General characteristics of bubble-tube interactions and stresses induced in the tube wall are described by considering typical simulation results.

“…Wang (1995) [8]. The proposed elastic mesh technique (EMT) based on the segments was showed by C. Wang (2002). EMT employed in conjunction with the boundary integral method (BIM) for the simulation of three-dimension bubble dynamics in which problems relating to severe mesh distortion as the bubble evolves are a common occurrence (C. Wang, 2002) [9].…”
