A Particle-Based Unified Model for Non-Newtonian Fluid Simulation

Through adding stress tensors into the Navier-Stokes equations, in this paper a non-Newtonian fluid simulation model is presented, it profits from the essential method of smoothed particle hydrodynamics, and can exhibit concurrently viscosity, elasticity and plasticity of non-Newtonian fluid, thereby a unified model for simulating non-Newtonian fluid is established. The proposed model are tested under various elastic and plastic parameter values, the experimental results show that non-Newtonian fluid with various elastic and plastic characteristic can be simulated realistically by using this model.
