Abstract The simulation of a thin film on a small scale surface that covers only part of the domain must incorporate the contact angle force acting on the border between wetted and dry parts of the surface. A method to reconstruct this contact line and interpolate the resulting force while using smoothed particle hydrodynamics as discretization method is derived, using only geometrical properties to calculate all needed parameters. The method is applied to several test cases to prove its applicability to the simulation of thin films.

在使用浅水方程和平滑粒子流体动力学的模拟中结合接触角力的新算法

摘要 在仅覆盖部分域的小尺度表面上模拟薄膜必须包含作用在表面润湿部分和干燥部分之间边界上的接触角力。推导出了一种重建此接触线并在使用平滑粒子流体动力学作为离散化方法的同时内插合成力的方法，仅使用几何属性来计算所有需要的参数。该方法应用于多个测试案例，以证明其适用于薄膜模拟。
