Two-group bubble size distribution evolution in vertical two-phase flow: Mechanistic model development and evaluation in a tight-lattice rod bundle

National Science Open
Two-phase flow with complex phase interfaces is commonly observed in both nature and industrial processes. The bubble size distribution (BSD) is a crucial parameter in gas-liquid two-phase flow, impacting various flow characteristics including ...

Modeling of turbulent transport term of interfacial area concentration in gas–liquid two-phase flow [PDF]

Nuclear Engineering and Design, 2012
Abstract A modeling of basic transport equation and constitutive equations of turbulent transport terms of interfacial area concentration was carried out. Based on the local instant formulation, interfacial area concentration was formulated in term of spatial correlation functions of characteristic function (local instant volume fraction) and its ...
