中文摘要：

概述相分离过程的离散 Boltzmann 方法研究进展。这部分研究内容，根据系统的成分，可分为单介质的两相分离和多介质的相分离；根据物理建模，可分为基于传统流体模型的LBM （lattice Boltzmann method）数值模拟和相分离系统的动理学建模与模拟；根据研究的侧重点，可分为方法（模型）研究和相分离过程研究。离散Boltzmann模拟所提供的非平衡行为特征为区分相分离的两个不同阶段提供了一个简洁、有效的物理判据，可用于不同类型界面的甄别与追踪技术设计。

英文摘要：

The studies on discrete Boltzmann modeling and simulation of phase separation are reviewed. According to the system component, the studies cover the single-component two-phase separation and the multi-component phase separation. According to the physical modeling, the studies cover the LBM （lattice Boltzmann method） simulations based on traditional hydrodynamic modeling and discrete kinetic modeling of the phase separation system. According to the main focus, the topic covers method/model studies and physical behavior investigations. The discrete kinetic modeling has brought some deeper insights into the phase separation process. The features of non-equilibriums obtained from discrete Boltzmann simulations can serve as some simple and effective physical criteria for dividing the two stages of phase separation, and can be used to discriminate and track various interfaces.
