A New Surface Tension Formulation for SPH

In this paper, a new surface tension formulation is presented for Smoothed Particle Hydrodynamics in fluid simulation, especially small-scale detailed fluid animation. The surface tension formulation is decomposed into three processes: (1) mesh smoothing exploited a Lagrangian operator in a volume-preserved way, (2) surface tension computation between the original mesh and smoothed mesh, (3) surface tension transfer from mesh vertices onto their neighbor particles. Experimental results show that the proposed surface tension formulation is effective and efficient for realistic simulations.
