Volumetric interfacial area prediction in upward bubbly two-phase flow
The authors propose a new model for different source terms appearing in the RHS of the volumetric interfacial area balance equation for bubbly flows. These source forms correspond to the turbulence-induced coalescence and breakup phenomena, as well as the gas expansion and phase change terms, including the nucleation of new bubbles on a heated wall. The model of the authors has been tested in comparison to three other models for the coalescence and breakup terms found in the literature, on two different experiments.
