Abstract

A submerged jet is utilized to disperse buoyant particle in a cylindrical receiver. A discrete particle model (DPM) is used for an axisymmetric domain. An unsteady DPM model is used on a steady-state fluid fully developed condition. The primary fluid (a vertical submerged liquid water jet on a cylindrical water bath) jet flow is fully developed and calculated by complete solution of Navier–Stokes equation. The primary flow is validated and verified (published earlier), and then an unsteady DPM is used to investigate the dispersion of particles. For validation, experiments were performed using Doppler velocimetry (LDV) and these data were generated at the Centre for Multiphase Processes, the University of Newcastle. Few turbulence models (\(k-\in \) realizable, SST models) generated results were compared. Using the models, dispersion of particle was predicted as a function of particle-to-liquid density ratio. For the same particle-to-liquid density ratio, it was found that the dispersion behavior is similar.
