提出了一种非混相流体表面张力的简单处理方法，如光滑粒子流体力学（SPH）和宏观伪粒子模型（MaPPM）。通过在不同流体的相邻粒子之间引入排斥力，表面张力自动产生，而每个相的简单状态方程仍然是可能的。利用流体体积法（VOF）对悬浮液中方形液滴的变形进行了对比模拟，验证了该处理方法的有效性。模型中表面张力与斥力强度参数之间的关系是用无底滴法得到的。
A simple treatment for surface tension in immiscible fluids is proposed for macro-scale particle methods such as smoothed particle hydrodynamics (SPH) and macro-scale pseudo-particle modeling (MaPPM). By introducing a repulsion between the neighboring particles of different fluids, surface tension arises automatically, while simple equations of state are still possible for each phase. This treatment is validated by comparative simulations on the deformation of a square liquid drop in suspension using the volume of fluid (VOF) method. The relationship between surface tension and the repulsion intensity parameter in our model is obtained by the sessile drop method.
