Numerical simulation of solid suspension flows in a horizontal pipe

Abstract eng:
The present work validates a numerical model used to describe the flow behavior of particle suspensions through horizontal pipes. The mixture of liquid water and polypropylene spheres is considered as single-phase and Newtonian fluid. The transport equation proposed by Phillips et al. [1] for the particle fraction is employed, including a term which accounts for buoyancy. Different flow conditions depending on the flow rate and initial particle concentration have been considered. The present simulations compare well to the experiments of Reghem [2] and improved the simulations of Darbouret [3].
