论文摘要
边界条件的实施是通过通道和复杂培养基建模流体流量最具挑战性的部分之一。在这里，我们表明，当墙壁与晶格的主轴对齐时，使用多组分晶格玻尔兹曼处理液壁相互作用的现有方法是准确的，但否则会失败。为了解决这个问题，我们扩展了以前针对多相模型制定的策略。例如，我们研究了两个维度在弯曲表面上的两个液滴的聚结。这里提出的策略与复杂几何形状中的二进制流有特殊相关性。
The implementation of boundary conditions is among the most challenging parts of modeling fluid flow through channels and complex media. Here, we show that the existing methods to deal with liquid-wall interactions using multicomponent Lattice Boltzmann are accurate when the wall is aligned with the main axes of the lattice but fail otherwise. To solve this problem, we extend a strategy previously developed for multiphase models. As an example, we study the coalescence of two droplets on a curved surface in two dimensions. The strategy proposed here is of special relevance for binary flows in complex geometries.
