液体溶液中生长的双组分气泡的稳态组成:自相似方法

Steady-state composition of a two-component gas bubble growing in a liquid solution: self-similar approach

G. Yu. Gor, A. E. Kuchma

摘要:

本文给出了气液两相溶液中双组分气泡生长的解析描述。得到了气泡半径与时间的渐近自相似关系和气泡周围溶解气体非稳态分布的解析表达式。我们表明,气泡生长的自相似制度的必要条件是恒定的,稳态组成的气泡。得到了稳态组成的方程。我们揭示了依赖于稳定状态的组合物上的气泡成分的溶解度定律。此外,通用的,独立于溶解度定律,表达式的稳态组成的情况下,得到的强过饱和,这是典型的均匀成核的气泡。

英文摘要:

The paper presents an analytical description of the growth of a two-component bubble in a binary liquid-gas solution. We obtain asymptotic self-similar time dependence of the bubble radius and analytical expressions for the non-steady profiles of dissolved gases around the bubble. We show that the necessary condition for the self-similar regime of bubble growth is the constant, steady-state composition of the bubble. The equation for the steady-state composition is obtained. We reveal the dependence of the steady-state composition on the solubility laws of the bubble components. Besides, the universal, independent from the solubility laws, expressions for the steady-state composition are obtained for the case of strong supersaturations, which are typical for the homogeneous nucleation of a bubble.
