Flow of Fluid in Gas-Bubble Columns

Abstract

The radial distribution of gas hold up and the circalations of liquid were measured by a sampling method in a gas-bubble column of 10cm diameter.
A theory of circulation is presented, which assumes a dual structure of turbulent core flow and a laminar wall sublayer.
Experimental results are used in the theory to calculate the effective turbulent viscosity in the column. Some other data are discussed by the theory to show the effect of column diameter on the viscosity and the liquid circulation.
