具有相变和变表面张力的不可压缩两相流

On incompressible two-phase flows with phase transitions and variable surface tension

Jan Pruess, Senjo Shimizu, Gieri Simonett, Mathias Wilke

摘要:

我们对具有热力学相变的不可压缩两相流的基本模型[10,11,12,16]的研究扩展到温度依赖的表面张力的情况。我们证明了在Lp-设置的适定性,研究问题的平衡的稳定性,并表明,不发展奇点的解决方案存在的全球性,如果其极限集包含一个稳定的平衡,它收敛到这个平衡的自然状态流形的问题,随着时间的推移到无穷大。

英文摘要:

Our study of the basic model for incompressible two-phase flows with phase transitions consistent with thermodynamics [10,11,12,16] is extended to the case of temperature-dependent surface tension. We prove well-posedness in an Lp-setting, study the stability of the equilibria of the problem, and show that a solution which does not develop singularities exists globally, and if its limit set contains a stable equilibrium it converges to this equilibrium in the natural state manifold for the problem as time goes to infinity.
