Discrete Particle Study of Turbulence Coupling in a Gas-Liquid Separator
SINOPSIS
A 3-D CFD investigation of particle-induced flow effects and liquid entrainment from an industrial-scale separator has been carried out using the Eulerian-Lagrangian (E-L) two-way coupled multiphase approach. A differential RSM was used to predict the gas phase turbulence field. The dispersed (liquid) phase was present at a relatively high mass loading (0.25) but low volume fraction (0.05). A discrete random walk (DRW) method was used to track the paths of the liquid droplet sampling bursts. It was found that gas phase deformation and turbulence fields were significantly impacted by the presence of the liquid particles; These effects have been parametrically quantified. It was also found that a very large number of independent steady-state DRW burst samples was needed (>1000) to make conclusions about entrainment. Known plant run conditions and entrainment rates validated the CFD method.
