Realistic simulation of multi-scale fluid-solid coupling
In this paper, we present a novel method for simulating middle- and small-scale details of incompressible viscous fluids and solid coupling. To animate the fluid model, we use the Smoothed Particle Hydrodynamics (SPH) method, which models the flow as a particle system in middle-scale, and based on it, we focus on the interaction between water and solid surface, especially the effects of absorption and adhesion. The absorption is simulated by absorption equations, which are mainly controlled by absorption, absorptivity, and saturation; and the adhesion is simulated by a linear spring and dashpot model, which can simulate the adhesive force. The proposed method works here to realistically animate the water gradually penetrating into the solid object, as well as some movements of runoff and flashing water. This new method thus improves existing fluid simulations, making them capable of generating new kinds of multi-scale interactions which have not realized in the present researches.
