Journal ArticleDOI
TL;DR: In this paper, a 32 mm dia vertical pipe with various forms of liquid outlet, namely a porous wall, a tapered outlet, and a square-edged outlet, was used to investigate the effect of churn flow on the penetration rate.

Journal ArticleDOI
TL;DR: In this paper, an assessment of the various viewpoints on the slug-to-churn flow transition in vertical upward flow in the light of recent experimental results obtained at Harwell Laboratory is made.

Journal ArticleDOI
TL;DR: In this article, the authors investigated the existence, development and translation of disturbance waves in upward, gas-liquid annular flows. And they found that the frequency of occurrence of the disturbance waves first increases away from the inlet as these waves form, reaches a maximum at a length between 7.5 and 15 pipe diameters, and then decreases again.

Journal ArticleDOI
TL;DR: In this article, an isokinetic probe was employed to measure the local mass fluxes of gas and entrained liquid droplets in the core region; pressure gradient was also measured.

Journal ArticleDOI
TL;DR: In this article, an experimental investigation into adiabatic gas-liquid counterflow in inclined and vertical rectangular ducts with a square-edged gas inlet is conducted, where water, methanol, propanol, air, argon, helium and hydrogen are used as working fluids.

Journal ArticleDOI
TL;DR: In this paper, a new steady state air-lifts model is proposed to predict the pressure gradient in the riser by a combination of specific models describing slug and churn flow, based on the available literature on two-phase flow.
