Counter-current gas-liquid flow in a vertical narrow channel—Liquid film characteristics and flooding phenomena
TL;DR: In this article, an experimental investigation of gas-liquid counter-current flow in a vertical rectangular channel with 10 mm gap, at rather short distances from liquid entry, is reported.
Journal ArticleDOI
Investigation of liquid film behavior at the onset of flooding during adiabatic counter-current air–water two-phase flow in an inclined pipe
TL;DR: In this article, the authors investigated the liquid film characteristics at the onset of flooding in an inclined pipe (16 mm i.d. and 2.2 m in length) using a constant electric current method and visual observation.

TL;DR: In this article, the effects of surface tension on flooding in counter-current two-phase flow in an inclined tube were investigated and an empirical correlation for flooding velocities was proposed that includes functional dependencies on surface tension and tube inclination.
Journal ArticleDOI
Characteristics of counter-current gas-liquid two-phase flow and its limitations in vertical annuli
TL;DR: In this paper, the complex flow behavior of counter-current gas-liquid flows in concentric vertical annuli over a wide range of gas and liquid flow rates was characterized by applying fast Fourier transform (FFT) on the associated pressure fluctuation signals.
Journal ArticleDOI
An analytical study on interfacial wave structure between the liquid film and gas core in a vertical tube
TL;DR: In this paper, a model for interfacial wave propagation for a liquid film on the wall of a vertical pipe and for a flowing gas in the central core was derived for a flat interface, and for traveling waves on the interface.

Journal ArticleDOI
Hydrodynamics and heat transfer of wavy thin film flow
TL;DR: In this article, the effect of sinusoidal and solitary waves on the heat transfer across the film was investigated and it was shown that the overall heat transfer coefficient is determined mainly by conduction through the film, rather than by recirculation, if any, under the waves.
Journal ArticleDOI
The effect of viscosity on the flooding conditions in wetted wall columns
TL;DR: The gas velocities for flooding in a wetted wall column have been measured as a function of liquid viscosity and flow rate as mentioned in this paper, and they were found to be somewhat higher than those predicted by D avidson and S hearer.
Journal ArticleDOI
Flooding in vertical two-phase flow
TL;DR: In this article, the authors describe a series of experiments to observe and photograph the flooding process and show that flooding occurs as a result of the formation and motion of a large disturbance wave on the surface of the liquid film.
Journal ArticleDOI
Theoretical investigation of the diameter effect on flooding in countercurrent flow
TL;DR: In this article, the CFDS-FLOW3D computational fluid dynamics code is used to determine the force exerted on a standing wave by gas flowing over it, and it is found that the drag on the wave is mainly due to the pressure variation around it and that it is a strong function of the channel dimensions.
