摘要：
We introduce a surface tension model for Smoothed Particle Hydrodynamics (SPH) using a Young-Laplace pressure boundary condition. Our model does not rely on fitting parameters and can be applied to different variants of SPH. We demonstrate its robustness and accuracy by simulating several notoriously difficult three-dimensional free surface flow problems driven by surface tension.(c) 2023 Elsevier B.V.
