Effect of Electrolyte Concentration on Bubble Size and Gas-Liquid Interfacial Area in Bubble Column

Tikrit Journal of Engineering Sciences, 2005
The optimum conditions of bubble column would be the ones that enhance mass transfer and this is accomplished by maximizing gas-liquid interfacial area. In the present work the effect of electrolyte concentration (aqueous solution of sodium chloride NaCl

Computational Fluid Dynamics Simulation and Experimental Measurement of Gas and Solid Holdup Distributions in a Gas-Liquid-Solid Stirred Reactor

, 2015
The lack of convincing computational fluid dynamics models and basic experimental data makes it difficult to design and scale up a gas liquid solid three-phase stirred reactor such as in environmentally benign bioleaching processes.

A simple correlation for prediction of the liquid slug holdup in gas/non-Newtonian fluids: Horizontal to upward inclined flow

, 2013
This paper studies the liquid slug holdup of gas/non-Newtonian fluids in horizontal and inclined pipes. The results of the study show that the liquid slug holdup significantly increases for a given mixture velocity as the liquid phase becomes ...

Feasibility Study on Downhole Gas–Liquid Separator Design and Experiment Based on the Phase Isolation Method

Applied Sciences, 2021
As oil exploitation enters its middle and late stages, formation pressure drops, and crude oil degases. In production profile logging, the presence of the gas phase will affect the initial oil–water two-phase flowmeter’s flow measurement results.
