Abstract

This paper introduces a numerical model for two- and three-dimensional simulations of sand drifting. The model is based on a homogeneous two-phase flow model, where the flow field is predicted by solving the Navier-Stokes equations for transient, incompressible, viscous flow in a general curvilinear coordinate system. The particle volume fraction is predicted by solving the convection/diffusion transport equation. The transport equations are discretized in a Eulerian reference frame using the Finite Volume method. Particles transported by suspension and saltation are both considered in the transport equation source term. An Erosion-Deposition algorithm is used to account for the transient change of the solid interface boundary, which
