Boundary integral method for 3D simulation of foam dynamics

Abstract. A Boundary Integral Method (BIM) for simulation of foam formation and dynamics in viscous flows is presented. The main features of the numerical method are: Nonsingular contour integration of the sin-gular single layer potential; Higher order approximation of the interface positions and the distance between the interfaces; Dynamic mesh reg-ularization. Presented are also results of foam-drop formation and its dynamic behavior in a viscous flow. They demonstrate the ability of the presented numerical method for simulation of polydisperse foam dynam-ics as well as dynamics of drops at very close distance.
