Bubble Disappearance Simulation Using Particle Methods

Abstract

These days, there are many researches related to fluid, which is expressed with particle methods, and one of them is a research on bubbles. Some are about the expression of bubbles, which flow in the water, move up, and disappear at random when they emerge on the water surface. These researches, however, are not the simulation based on the physical phenomena. Therefore, we have simulated bubble disappearance with physical based model using particle methods. In the model, a bubble is composed of air and water particles, and water particles that touch air particles constructing the bubble inside on water surface are considered as bubble surface particles. Then, bubbles can move up on the water surface and disappear by considering surface tension and gravity that work on the bubble surface particle.
