ABSTRAKT

The interfacial transfer terms are one of the important aspects of the two-fluid formulation modelling. However, there exist considerable difficulties in this area both in terms of experiments and modelling. The first step in the right direction is to consider that the interfacial transfer terms are proportional to the interfacial area concentration and driving force. This approach effectively separates the first order geometrical effect on the interfacial transfers from the local driving forces. Hence more mechanistic modelling of the interfacial area concentration, the available experimental data, measurement methods and modelling are reviewed and new directions are indicated.
