A CFD-Population Balance Model for the Simulation of Kühni Extraction Column
Abstract
In this work, computational fluid dynamics (CFD) calculations coupled with DPBM are compared to LLECMOD (L. iquid-L. iquid E. xtraction C. olumn MOD. ule) simulations and to Laser Induced Fluorescence (LIF) measurement of the phase fraction using an iso-optical system of calcium chloride/water and butyl acetate. The results show a good agreement between the simulations and experimental data. The CFD requires a high computational load compared to LLECMOD, but gives local information about the droplet size and the phase fraction and is independent from geometrical constraints.
