APPLICATION OF THE CONTINUOUS SPECIES TRANSFER MODEL TO LIQUID-LIQUID EXTRACTION

Mass transfer in multiphase flows is an important subject in the process industry. For that matter, the Continuous species transfer model has been applied to study these systems. The model uses a one field equation to estimate the concentration distribution in each phase, where a term called CST-flux is defined to account for the concentration jump at the interface of these phases. In this work we use the CST model to predict the mass transfer process in a liquid-liquid extraction problem. The numerical velocity and concentration profiles were validated against analytical models.
