Abstract

We perform linear analysis of morphological stability of a circular bubble growing nonstationary in a 2D liquid disregarding the variation of temperature and viscosity. The media are treated as incompressible, and the pressure in the bubble is assumed to be constant. Beginning from a certain critical size (kinetic spinodal), a transition from stable to unstable growth is observed, which differs in principle from the known solution for the 3D case. An approximate equation is derived for calculating the spinodal.

动态生长条件下气泡表面的形态稳定性。2D手机壳

摘要

我们对在2D液体中非平稳生长的圆形气泡的形态稳定性进行线性分析，而无需考虑温度和粘度的变化。介质被视为不可压缩，并且气泡中​​的压力假定为恒定。从一定的临界尺寸（动能节距）开始，观察到了从稳定生长到不稳定生长的转变，其原理与3D情况下的已知解决方案不同。导出一个近似方程式以计算旋节线。
