The effect of horizontal gas flow on liquid dropping flow in the two-dimensional packed bed was studied through cold model experiments. Liquid flow region enlarged and moved in the direction of the gas flow during its descent. Both displacement and dispersion of the liquid flow augmented with increase of gas flow rate and liquid flow rate. A mathematical model of the liquid dropping flow was developed, in which the packed bed is simulated with a flow network whose unit mesh size corresponds to a particle diameter. Relations of superficial velocity of gas and liquid to transit probability and turbulent diffusion ratio of liquid drops which predominate their transit paths were determined on the basis of the experimental results. The results of the mathematical simulation were in good agreement with the experimental results.
