Abstract
Mass transfer coefficients from liquid phase to particles in packed beds have been investigated for gas continuous two phase flow with a stationary gas phase. 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 were measured by the limiting current technique. Mass transfer coefficients in two phase flow became greater than those in liquid-full single flow, and were arranged by modifying the Reynolds number and the Sherwood number, considering the actual liquid velocity among particles and the ratio of the mass transfer area to the sectional area of liquid film.
