Influence of the Water Nature on the Two-phase Flow in an Air-lift Column

Djimako Bongo, Alexis Mouangué Nanimina, Nandiguim Lamai, Togdjim Jonas, Bonaventure Danoumbe & J. Y. Champagne · Physical Science International Journal · 2020

The aim of this study is to determine the phase indicator functions of a two-phase flow in an air-lift vacuum column. The outcome of this study is to master the hydrodynamics in a vertical column when determining the size, the velocities of the bubbles and the void rate then the...
