摘要：

The purposes of this report are to establish the measuring systems for liquid holdup and to obtain the relationship between the flow and the mass-transfer coefficients for gas continuous two-phase flow in packed beds. Liquid holdup existing in packed beds was obtained by using the method of neutron attenuation and a correlation for liquid holdup was presented as a function of the Reynolds number and the Galilei number. Liquid-to-particle mass-transfer coefficients for gas continuous two-phase flow depended on the liquid holdup, and the modified correlation for mass-transfer coefficients was obtained by modifying the Reynolds number and the Sherwood number, considering the actual liquid velocity in packed beds and the ratio of the mass-transfer area to the sectional area of flow.
