摘要

Abstract

Based on the multi-class bubble model and the assumption that bubbles rise in plug flow during dynamic gas disengagement

the function between gas holdup and time was obtained by using the pressure transducing technology. The plot obtained by the model agreed with the plot obtained by experiment. The pressure transducing technology is shown to be a good method for the measurement of hydrodynamics in a bubble column. The changes of gas holdup

large bubble holdup and small bubble holdup

bubble rising velocity with superficial gas velocity and liquid viscosity were obtained by using dynamic gas disengagement.
