Molecular gas dynamics analysis of collapse and rebound of spherical bubble filled with vapor and gas

Abstract

The aim of this study is to simulate the dynamics (collapse and rebound) of a spherical bubble filled with condensable and non-condensable gas. For bubble motion, we utilize the Fujikawa and Akamatsu equation; for the gas-mixture flow in the bubble, we utilize the Boltzmann equation for gas mixture. In this paper, we show that the numerical method for the equations and numerical results for the bubble collapse problems.
