Abstract
AbstractThis work is a model assessment study considering two major hydrodynamic parameters: the holdup of the dispersed phase and the Sauter diameter. This is done for two different types of extraction columns, namely, the rotating disc contactor (RDC) and the Kühni column, using different drop breakup and coalescence models in a droplet population balance model. Based on the film drainage models for undeformable (spherical drops) and deformable drops with partially mobile interfaces, different simulations have been performed and the results compared with experimental values. The agreement between the experimental observation and the simulation is encouraging and the used models have proven to be suitable to predict holdup and Sauter diameter profiles for the system toluene/water.
