Simulation of bubbles with floating and rupturing effect for SPH

ABSTRACT

In this paper, we present a new SPH (Smoothed Particle Hydrodynamics) method for multi-fluid. Our idea is to extend an Implicit Incompressible SPH (IISPH) for multi-fluid using a particle density. By replacing the formulation to solve the pressure poisson equation (PPE) in IISPH with a new equation based on particle densities, it realized to simulate more stable multi-fluid which considers of higher density ratios, incompressibility, and large time step. This paper shows the simulation of bubble behaviors such as rising, merging, floating, and rupturing, using our proposed method. Additionally, we also present a method to represent a thin film generated by the floating bubbles on the liquid surface by introducting an anisotropic filter for the computation of the surface tension.
