Local formulation and measurements of interfacial area concentration in two-phase flow
TL;DR: In this paper, the local instantaneous formulation of the interfacial area concentration is introduced, and time and spatial averaged area concentrations are derived, and the local ergodic theorem is obtained for stationary developed two-phase flow based on the two-fluid model.
Local instant formulation of two-phase flow
TL;DR: The local instant formulation of mass, momentum and energy conservations of two-phase flow has been developed in this paper, where the source terms at the interface are defined in terms of the local instant interfacial area concentration.
