In the recent times, the boundary integral method has been utilised extensively in the study of bubble dynamics. This paper presents a modified form of the boundary integral method to model the motion of a bubble close to a fixed rigid structure. The resulting integral equations are solved using the boundary element method, and the system is integrated through time using a simple Euler scheme. Finally, the results of the model are presented to predict the motion of a bubble in a number of typical axisymmetric situations. Copyright © 1999 John Wiley & Sons, Ltd.
