Flow characteristics of gas–liquid two phase plunging jet absorber–gas holdup and bubble penetration depth
A gas-liquid two phase plunging jet is formed through a gas sucking type multi-jet ejector nozzle. In this study, the effects of various conditions in the multi-jet ejector nozzle, the column diameter, and the liquid jet length on penetration depth of air bubblesl B and gas holdup hG in a gas-liquid two phase plunging jet absorber were studied experimentally. Consequently, empirical equations concerningl B and hG were obtained, respectively. These equations agree with the experimental data with an accuracy of ±20% forl B and ±25% for hG.
