In this paper, an original phase-field lattice Boltzmann scheme for a system composed of two immiscible and incompressible fluids interacting with moving solids is developed, presented, and tested for the first time. The proposed approach is benchmarked against experimental data and smoothed particle hydrodynamics simulations of four well-established two-dimensional problems where a rigid body interacts with the interface between the two fluids. The outlined methodology represents a very good candidate to perform fluid-structure interaction simulations of hydrodynamic stability problems as well as water-entry and water-exit problems.

一种求解进水和出水问题的相场格子Boltzmann方法

在本文中，首次开发、提出和测试了由两种不混溶和不可压缩流体与移动固体相互作用组成的系统的原始相场格子玻尔兹曼方案。所提出的方法以四个成熟的二维问题的实验数据和平滑粒子流体动力学模拟为基准，其中刚体与两种流体之间的界面相互作用。概述的方法代表了一个很好的候选者来执行流体动力稳定性问题以及进水和出水问题的流固耦合模拟。
