One-group interfacial area transport equation for horizontal two-phase flow with 90-degree bend

open access: yes, 2007
The two-fluid model is used in the current thermal-hydraulic system analysis codes to perform detailed assessment of nuclear reactor safety. One of the major shortcomings of the two-fluid model has been the lack of an accurate and dynamic closure ...

Modeling of interfacial area concentration and interfacial momentum transfer: Theoretical and experimental study

open access: yes, 1997
The interfacial transfer terms are important for modeling the dynamic coupling between the phases in a two-fluid formulation. The geometric factor of these transfer terms is recognized by the interfacial area concentration.

The Effect of Periodic Segmentation Cracks on the Interfacial Debonding: Study on Interfacial Stresses

open access: yes, 2006
Hard coatings on relatively soft substrate always face the danger of debonding along the interface. Interfacial stresses are considered to be the initial driving force for the interfacial debonding of the relatively strong bonded coatings.

Adsorption and Dilational Viscoelasticity of Saponin at the β-Pinene/Water and Air/Water Interfaces

open access: yesColloids and Interfaces
Understanding adsorption and interfacial properties of surface-active agents at interfaces is crucial to the formation and stability of colloidal systems such as emulsions and foams. In this work, interfacial tension and viscoelasticity of saponin at the

Heterogeneous nucleation and growth kinetics of struvite in anaerobic digestate: Role of diatomaceous earth as a model mineral interface

open access: yesDesalination and Water Treatment
Anaerobic digestion (AD) is widely applied for sludge stabilization and energy recovery, but its operation is often affected by phosphate scaling, particularly struvite (MgNH4PO4·6H2O) crystallization.
