Interfacial area concentration in gas-liquid metal two-phase flow
Experimental and Computational Multiphase Flow, 2021The characterization and modelling of the flow features in gas and heavy liquid metal two-phase flow are required for the development of next generation nuclear reactor systems. In this study, the past experimental studies performed in the gas-liquid metal two-phase flow are reviewed, and the void fraction and interfacial area concentration (IAC ...

Interfacial area concentration in bubbly flow
Nuclear Engineering and Design, 1990Abstract Interfacial area concentration is one of the most important parameters in two-phase flow. It is related to mass, momentum and energy transfer at the interface. In bubbly flow, it has close relation to bubble diameter. Interfacial area concentration was measured with particular attention to bubble diameter at inlet.

Measurement of interfacial area concentration in subcooled liquid-vapour flow
Nuclear Engineering and Design, 1994Abstract In two-fluid modelling, accurate prediction of the interfacial transport of mass, momentum and energy is required. Experiments were carried out to obtain a database for the development of interfacial transport models, or correlations, for subcooled water-steam flow in vertical conduits.

Modeling and measurement of interfacial area concentration in two-phase flow
Nuclear Engineering and Design, 2010Abstract This paper presents experimental and modeling approaches in characterizing interfacial structures in gas–liquid two-phase flow. For the modeling of the interfacial structure characterization, the interfacial area transport equation proposed earlier has been studied to provide a dynamic and mechanistic prediction tool for two-phase flow ...

Numerical evaluation of interfacial area concentration using the immiscible lattice gas
Nuclear Engineering and Design, 1999Abstract The phase separation in a Couette flow and the mixing of two phases in a cavity flow are simulated numerically using the immiscible lattice gas, which is one of the discrete methods of using particles to simulate two-phase flows. The interface is defined as the lattice sites between two phases, and the interfacial area concentration is ...

Modeling interfacial area concentration in bubbly flow
Physics of FluidsAccurate mass, momentum, and energy transfer predictions through gas and liquid interfaces are critical in simulating gas–liquid two-phase flow dynamics. Since the interfacial transfer rates depend on the interfacial area concentration (IAC), it is essential to model the IAC accurately for robust two-phase flow analyses.

Local formulation and measurements of interfacial area concentration in two-phase flow
International Journal of Multiphase Flow, 1986The local instantaneous formulation of the interfacial area concentration has been introduced based on the concept of a distribution. Using a delta function and the interface equation, the local instantaneous interfacial area concentration has been defined.

Benchmarking of the five-sensor probe method for a measurement of an interfacial area concentration
Experiments in Fluids, 2006Interfacial area concentration (IAC) is one of the most important parameters in the two-phase flow models. Five-sensor probe method is a useful measurement technique to measure an IAC. It is essentially based on the four-sensor probe method but it is improved by adapting one more sensor.

Closures for the Bubble Size Distribution and Interfacial Area Concentration
2015This chapter is devoted to the presentation of the closure laws for the interfacial area transport equation and other multi-size bubble models. Considering first the single size case, the different forms of the interfacial area transport equation are recalled and their closure laws are reviewed.
