CFD methodology for sedimentation tanks: The effect of secondary phase on fluid phase using DPM coupled calculations

► We simulate the 3D hydrodynamics and flow behaviour in a sedimentation tank. ► We examine the interaction among continuous and discrete phase. ► Particles with Stokes number >1 affect the flow field. ► Increasing particle size will generate new vortices in the flow field. ► When particle size increases fluid velocity diverge from single phase flow.
