Modeling sensitivity in prediction of interfacial area concentration in boiling flow
Progress in Nuclear Energy, 2021Abstract A comprehensive review and validation of three approaches to predict interfacial area concentration in subcooled boiling flow are presented. The three methods are geometry-based semi-empirical correlations, empirical correlations, and the interfacial area transport equation (IATE).

Interfacial area concentration in boiling bubbly flow systems
Chemical Engineering Science, 2006The interfacial area, which describes available area for the interfacial transfer of mass, momentum and energy, is a crucial parameter in a two-fluid model formulation. From this point of view, this study performed (i) extensive survey on existing models and correlations developed for boiling bubbly flows, (ii) extensive survey on existing interfacial ...

Interfacial area concentration in annular two-phase flow
International Journal of Heat and Mass Transfer, 2007Abstract Accurate prediction of the interfacial area concentration is essential to successful development of the interfacial transfer terms in the two-fluid model. The interfacial area concentration in annular flow and annular-mist flow is especially relevant to the transition process to the liquid film dryout, which might lead to fatal problem in ...

Interfacial area concentration of bubbly flow systems
Chemical Engineering Science, 2002Abstract Although gas–liquid bubbly flows are encountered in various engineering fields, there are very few established theoretical foundations on the interfacial area concentration, which have been supported by extensive experimental data. From this point of view, a simple equation for the interfacial area concentration has been derived from the ...

Interfacial area concentration in steady fully-developed bubbly flow
International Journal of Heat and Mass Transfer, 2001Abstract Although bubbly flows are encountered in various engineering fields, there are very few established theoretical foundations on the interfacial area concentration, which have been supported by extensive experimental data. From this point of view, a simple equation for the interfacial area concentration under steady fully-developed bubbly flow

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 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 ...

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.
