Numerical simulation of slurry flows in heterogeneous and saltation regimes in horizontal pipelines

Abstract

In this work, the simulation of a two-phase liquid-particles flow is performed using an Eulerian- Eulerian model to predict the complex flow behavior where both particle concentration and particle velocity profile are shown and compared with experimental data. One of the main concerns during implementation of pipeline transportation of multiphase mixtures the is assurance of the flow, where the formation of particle fixed beds should be strongly avoided due to its disadvantageous and damaging effects on the flow, which mostly occur at the bottom sides of the pipeline walls.
