CFD modelling of pulsed sieve plate liquid extraction columns using OPOSPM as a reduced population balance model

摘要

The simulation of pulsed sieve plate liquid-liquid extraction columns is performed by coupling a 2D-CFD simulation with a reduced population balance method. In this regard, the One Primary One Secondary Particle Method (OPOSPM) is utilized and implemented in Fluent 17.1 commercial software as a special case of the general Sectional Quadrature Method Of Moments (SQMOM). The droplet-droplet interactions (breakage and coalescence) are taken into account using OPOSPM, while the required information about the velocity field and energy dissipation is estimated by a CFD model. A positive validation of the column hydrodynamics behaviour is with experimental data at different operating conditions.
