Prediction of interfacial area concentration in a small diameter round pipe
International Journal of Heat and Mass Transfer, 2019Abstract Accurate prediction of interfacial area concentration (IAC) is of great importance in the two-fluid model. As a promising IAC prediction method, the interfacial area transport equation (IATE) was developed to dynamically predict the IAC and to eliminate the shortcomings of the flow regime-based IAC correlations, which is currently used in ...

An experimental study on local interfacial area concentration using a double-sensor probe
International Journal of Heat and Mass Transfer, 2005Abstract Interfacial area concentration is an important parameter in modeling the interfacial transfer terms in the two-fluid model. In this paper, the interfacial area concentration, void fraction, and bubble Sauter mean diameter for air–water bubbly flow through a vertical transparent pipe with 40 mm internal diameter was investigated ...

Interfacial area concentration in gas–liquid bubbly to churn-turbulent flow regime
International Journal of Heat and Fluid Flow, 2012Abstract There are very few established correlations to predict the interfacial area concentration beyond the bubbly flow regime in cap-slug and churn-turbulent flow regimes. Present study shows a systematic approach to estimate the interfacial area concentration in bubbly, cap-slug and churn-turbulent flow regimes.

The interfacial area concentration (IAC) is one of the most important parameters in the two-fluid model for two-phase flow analysis. The purpose of this study is to develop the local IAC measuring method by using the five-sensor conductivity probe. In this paper, the mathematical approach of the five-sensor conductivity probe method for measuring the ...

Abstract The sensitivity study on a double-sensor conductivity probe for the measurement of local interfacial area concentration, has been carried out by considering the effects of bubble lateral motions and probe spacing. The measurable value was rigorously related to the local bubble interface velocity in the surface normal direction, and the ...

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.

Interfacial area concentration and bubble size distribution measurement using tomography technique
International Journal of Multiphase Flow, 2021Abstract Interfacial area concentration (IAC) and bubble size distribution (BSD) are two important parameters in two-phase flow simulations. High-speed tomography techniques, mainly including wire-mesh sensor and ultrafast X-ray imaging in this stage, are advanced measurement devices, which can measure the instantaneous phase distribution in the ...
