Application of Two‐Group Drift‐Flux Model to Improve Two‐Group Interfacial Area Concentration Model for Dispersed Gas–Liquid Flows in Rod Bundles

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
Understanding interfacial area concentration (IAC) is crucial for analyzing gas–liquid interfacial transfer processes of mass, momentum, and energy. A two‐group IAC model, which considers the dependence of bubble size on two‐phase flow characteristics, has demonstrated outstanding potential in modeling the IAC in dispersed two‐phase flows. Based on the
