Abstract

The three-dimensional motion of underwater two bubbles is directly simulated using the Level Set method. The interaction of the bubbles and their wakes are studied by changing their position and size. The behaviors such as distortion

attraction

and repulsion of the two bubbles are obtained and the calculated values of the bubbles velocity agree well with the empirical correlations. The interaction in fluid dynamics between the wakes of the two bubbles is described by the velocity field around the bubbles. For the two bubbles placed horizontally or vertically

the bubbles will converge when more than 50% of the projection area of the lower bubble enters the wake of the upper bubble.
