流体畴粗化的普适性:汽液相变的情况

Universality in Fluid Domain Coarsening: The case of vapor-liquid transition

Suman Majumder, Subir K. Das

摘要:

本文研究了单组分Lennard-Jones流体汽液相变后相分离动力学过程中的畴生长。在适当地将从广泛的分子动力学模拟获得的连续快照映射到简单的立方晶格后,对结果进行了分析。对于近临界淬火互连域形态观察。一个短暂的缓慢扩散增长期之后是线性粘性流体动力学增长,持续一段较长的时间。这一结果是矛盾的较早的包容性报告的后期增长指数1/2的问题的唯一性的非平衡普遍性的液-液和汽-液转变。

英文摘要:

Domain growth during the kinetics of phase separation is studied following vapor-liquid transition in a single component Lennard-Jones fluid. Results are analyzed after appropriately mapping the continuum snapshots obtained from extensive molecular dynamics simulations to a simple cubic lattice. For near critical quench interconnected domain morphology is observed. A brief period of slow diffusive growth is followed by a linear viscous hydrodynamic growth that lasts for an extended period of time. This result is in contradiction with earlier inclusive reports of late time growth exponent 1/2 that questions the uniqueness of the non-equilibrium universality for liquid-liquid and vapor-liquid transitions.
