TL;DR: In this paper, the average thickness of thin liquid film has been studied as functions of both gas and liquid phase velocities, and a semi-empirical model has been proposed to predict the disturbance wave height.

TL;DR: In this paper, an adiabatic upward air-water flow experiment was performed on a vertical pipe with 25.4mm inner diameter to investigate the interface structure and characteristics, including time-averaged void fraction, interfacial area concentration, bubble interfacial velocity and Sauter mean diameter.

TL;DR: In this paper, a new liquid film thickness model has been developed for vertical annular flow in pipes based on three databases, which includes the pressure, liquid and gas velocities, diameter, and viscosity effects on the film thickness.

TL;DR: In this article, a new objective flow regime identification method based on fuzzy C-means (FCM) clustering algorithm and ReliefF attribute weighting algorithm was proposed for co-current upward and downward two-phase flow.

TL;DR: In this paper, the authors investigated the transition mechanism of bubbly flow to slug flow and found that the changes of bubble size and shape may result in the decrease of velocity ratio in bubble flow.
