Abstract

We have simulated rupture behavior of a bubble by using a particle method. Bubbles in the water are composed of air particles surrounded by water particles; however, bubbles on the water surface are composed of water particles surrounded by air particles and the air. In order to simulate rupture behavior of a bubble, film particles are defined as the particles that construct bubbles on the water surface, and the simulation can be performed by taking into account the connection between film particles. In addition, the density ratio of water and air is so large that it is difficult to analyze the behavior of water and air particles at the same time. Therefore, we have visualized rupture behavior of a bubble by combining two-phase behavior after calculating the pressure of water and air particles separately.
