摘要：

The shallow water equations are discretized using the smoothed particle hydrodynamics (SPH) method. This combination is applied to the simulation of a small scale thin fluid film on partially wetted and curved surfaces. The simulation incorporates all relevant forces, including surface tension and the contact angle force at the separating line between dry and wet regions. The resulting rivulet flow is validated using theoretical findings and measurements carried out elsewhere. (C) 2019 Elsevier B.V. All rights reserved.
