Abstract

This paper examines the influence of physical parameters on the collapse dynamics of a spherical bubble filled with diatomic gas ( $κ = 7 / 5$ ). The problem is formulated by the Rayleigh–Plesset dynamical equation, whose numerical solutions are carried out by Maple. Our studies show that each physical parameter affects the bubble collapse dynamics in different degree, which reveals that bubble collapse dynamics must considers all the parameters including liquid viscosity, surface tension, etc, else the outcome cannot be trusted.

物理参数对球形气泡崩塌的影响

本文研究了物理参数对充满双原子气体(κ=7/5)的球形气泡坍缩动力学的影响。该问题由Rayleigh-Plesset动力学方程表示，其数值解由Maple实现。我们的研究表明，各个物理参数对气泡崩塌动力学的影响程度不同，这表明气泡崩塌动力学必须考虑液体粘度、表面张力等所有参数，否则结果不可信。
