摘要 为了获取更稳定和真实的流体表面微观特性,本文提出了一种基于隐式不可压缩SPH的表面张力和吸附力方法。该方法给出了稳定和快速的表面张力模型而且解决了未考虑吸附力的问题。表面张力模型考虑分子聚力与斥力和表面区域最小化两种作用,同时加入吸附力来更好的展现表面的微观特性。表面张力与吸附力模型与隐式不可压缩SPH算法相结合,提高了模拟的稳定性与效率。实验结果表明,该方法在多种场景均能较好的表现流体的表面特性,同时兼顾了时间效率和稳定性。

Abstract: In order to capture stable and realistic microscopic features of fluid surface, a surface tension and adhesion method based on implicit incompressible SPH (smoothed particle hydrodynamics) is presented in this paper. It gives a steady and fast tension model and can solve the problem of not considering adhesion. Molecular cohesion and surface minimization are considered for surface tension, and adhesion is added to show the microscopic characteristics of the surface. To simulate surface tension and adhesion stably and efficiently, the surface tension and adhesion model is integrated to an implicit incompressible SPH method. The experimental results show that the method can better simulate surface features in a variety of scenarios compared with previous methods and meanwhile ensure stability and efficiency.
