A density-correction method for particle-based non-Newtonian fluid

Abstract

We propose a novel non-Newtonian fluid simulation method for SPH. The variable viscosity under shear stress is achieved using a viscosity model known as Cross model. By adopting a density-correction scheme, larger time step is available for simulation. The achieved results show that both Newtonian fluid and non-Newtonian fluid could be achieved by our model. Furthermore, density-correction scheme improves the stability and efficiency of simulation significantly.
