The application of one-group and two-group interfacial area transport equations (IATE) coupled with the computational fluid dynamics (CFD) solver to describe the temporal and spatial evolution of the two-phase geometrical structure is presented. Available mechanistic models of interfacial area sink and source terms in open literatures as well as our newly developed models are assessed with the CFD EAGLE code. Numerical predictions of the models are evaluated against experimental data of the VAWL facility for vertical-upward air-water pipe flow with an inner diameter of 80 ㎜. Better agreement between measured and predicted distributions of void fraction, interfacial area concentration (IAC) and bubble diameter is achieved with our models.
