A NUMERICAL METHOD FOR MODELLING THE MOTION OF A SPHERICAL BUBBLE

This paper presents a numerical method for predicting the motion of a spherical bubble close to a rigid structure. The velocity potential in the fluid due to the motin of the bubble is represented by a source and a dipole located at the centroid of the bubble. This leads to a coupled system of differential equations for the bubbble radius and the location of its centroid. This system of equations can be solved using an appropriate numerical scheme.
