Proc. ASME. ICONE29, Volume 15: Student Paper Competition, V015T16A111, August 8–12, 2022
Paper No: ICONE29-93313
..., the analysis of the phase distribution characteristics such as the void fraction and the interfacial area concentration is helpful to research the two-fluid model and interfacial area transport equation. Based on the completed flow pattern experiment, an air-water two-phase flow characteristic experiment...

Proc. ASME. ICONE28, Volume 4: Student Paper Competition, V004T14A029, August 4–6, 2021
Paper No: ICONE28-64342
...Abstract Abstract The interfacial area concentration (IAC) is an important parameter in the calculation of interfacial transfers in two-fluid model, which can affect the accuracy of the boiling simulations. In this paper, an improved IAC model based on drag force and drift velocity is obtained...

Paper No: ICONE2020-16836
... and the interfacial area concentration are investigated and benchmarked with the experimental data measured using the four-sensor conductivity probe. It is concluded that CFD simulation can predict the characteristics distributions of void fraction and interfacial area concentration and their development downstream...

Paper No: ICONE10-22313
... parameters include void fraction (α), interfacial area concentration (a i ), bubble frequency (f b ), bubble velocity (U b ) and bubble Sauter mean diameter (D sm ). The radial profiles of these parameters and their development along the axial direction reveals the structure of the two phase mixture...
