• 1115 Numerical Simulations of Single Bubble Dynamics Accompanied with Phase Change Based on Molecular Gas Dynamics(2)

抄録

The collapse and rebound of a spherical bubble filled with a noncondensable gas or condensable gas (vapor) were investigated by combining bubble dynamics and molecular gas dynamics. The polyatomic version of Gaussian-BGK Boltzmann equation was utilized for a gases vapor inside the bubble, while Fujikawa & Akamatsu's equation was utilized for the motion of the bubble. These equations were solved numerically with the kinetic boundary condition including a condensation coefficient that is an important parameter for phase change processes. The result shows that the condensation at a vapor-liquid interface of a vapor bubble is essential for the mechanism of collapse and rebound of the bubble.
