Fast and Stable Surface Feature Simulation for Particle-Based Fluids

In order to efficiently and realistically capture microscopic features of fluid surface, a fast and stable surface feature simulation approach for particle-based fluids is presented in this paper. This method employs a steady tension and adhesion model to construct surface features with the consideration of the adsorption effect of fluid to solid. Molecular cohesion and surface area minimization are appended for surface tension, and adhesion is added to better show the microscopic characteristics of fluid surface. Besides, the model is integrated to an implicit incompressible smoothed particle hydrodynamics (SPH) method to improve the efficiency and stability of simulation. The experimental results demonstrate that the method can better simulates surface features in a variety of scenarios stably and efficiently. © 2019 Editorial Department of Journal of Beijing Institute of Technology .
