Abstract

Settling of particles in non-Newtonian fluid is important in the field of mining and dredging. A Volume of fluid CFD code is adapted to simulate the settling of particles under shear. A rheological model is implemented that includes the influence of the sand concentration on the yield stress and plastic viscosity. The code is capable of simulating the shear settling behaviour of a mixture of fine and coarse grained particles.
