本章探讨了在固体表面上模拟液滴动力学的各种方法，并强调了此类系统预测建模的关键挑战是捕捉移动接触线和相关接触角的复杂行为。模拟流体流动的常用方法是将所涉及的流体视为连续介质，即没有潜在的分子组成。本章探讨了与接触角相关的一些特征和现象，这些特征和现象使得表面上液滴的预测模拟变得如此具有挑战性。与锐界面模型相反，扩散界面模型开始的观点是，液体界面具有有限的厚度，在该厚度上，热力学变量在两侧的体积值之间平滑但快速地变化。格子玻尔兹曼（LB）方法是一种介观方法，它已被应用于非常广泛的问题，包括许多研究的滴动力学和润湿。
This chapter explores various methods for simulating drop dynamics on solid surfaces, and highlights that the key challenge in predictive modeling of such systems is in capturing the complex behavior of moving contact lines and the associated contact angles. The usual approach to simulating fluid flows is to consider the fluids involved as continuous media, that is, without an underlying molecular composition. The chapter explores some of the features and phenomena related to contact angles that make predictive simulation of drops on surfaces so challenging. In contrast with the sharp‐interface models, diffuse‐interface models begin with the perspective that liquid interfaces have a finite thickness over which thermodynamic variables change smoothly but rapidly between the bulk values on either side. The lattice Boltzmann (LB) method is a mesoscopic method, which has been applied to a very diverse range of problems including many studies of drop dynamics and wetting.
