By treating an element of structured packing as a three-dimensional node net and analyzing the flow patterns of 2 kinds of liquid stream in the net

i.e. net line flow and node flow

the liquid distribution model for an element of structured packing was eslablished.By transforming the liquid exchange between packing and column wall into that between the node net of packing and the node net of column wall

the liquid distribution model for the column wall zone around a packing element was presented.The boundary conditions for the liquid distribution problem of structured packed columns were proposed. The liquid distribution model for corrugated sheet structured packed columns was thus composed of the above two models and relevant boundary conditions. Three model parameters were estimated by using the simplex method. The calculated results agreed very well with the experimental data

that is to say

the mathematical model could describe the liquid flow behavior in corrugated sheet structured packed column correctly.
