Abstract

A mathematical model of liquid dropping flow in a two-dimensional packed bed was developed, in which distribution of liquid generating points, wall and impermeable region have been considered. The model was combined with the gas flow model in order to analyze the phenomena in the dropping zone in a blast furnace.
The influence of gas and liquid flow rate on the liquid flow was examinèd through cold model experiments and the simulation results were validated by the experimental results.
On the basis of the simulation, liquid flow distribution in the blast furnace becomes uniform through dropping to the furnace bottom. Flooding tends to occur just below the cohesive layer.
