tapered bed

In order to recognize the flow characteristics in a tapered affinity adsorption bed, FLUENT software was used in numerical simulation for the liquid-solid two phases flow. A two-fluid model of the liquid-solid in the ( tapered) bed was established based on the theory of two-phase flow.
