This paper has studied the flow regimes and their transitions in upward gas-liquid two-phase
flows in vertical rod bundle flow channels. The past experimental observations on the flow …

The detailed understanding and accurate modeling of the upward two-phase flows in
vertical rod bundle flow channels are significant for various industrial applications, such as …

In this study, the vertical upward air–water two-phase flow tests have been carried out to
investigate the distribution of local and global void fractions in a rod bundle channel under …

In this paper, the influence of the phase distribution imposed as an inlet boundary condition
in a two-phase flow simulation is investigated. Firstly, a new inlet model is proposed which …

This study examines modeling uncertainty in slug flow due to the use of a uniform density in
neutronic simulations. We created a detailed neutronic model of the slug flow regime, in the …

The variation of void fraction and interfacial area concentration can affect the heat transfer,
mass transfer, and interfacial drags. This study investigates the air-water two-phase flow in …

In numerical research about two-phase flow in tube bundles, mainly two trends are
distinguishable. On the one hand, some studies start from the assumption that only relatively …

The author would like to express sincere gratitude to his supervisor Prof. Toshihiro
Yamamoto for giving him the invaluable opportunity to come to Kyoto University to perform …

Heat exchangers and piping are commonly used in industrial applications such as power
plants, oil and gas transport or process industry. When the pipes in these applications are …

The gas-liquid two-phase flow behaviors are always associated with its dynamic void
fraction, such as flow resistance, heat transfer coefficient, phase distribution, critical heat flux …
