AbstractA novel capillary array model is proposed to shed light on the development of the maldistribution of cocurrent downward gas-liquid flow and the hysteretic performance behavior in a packed column. The model is based on the principle of nonequilibrium thermodynamics and in combination with lateral random walk of elemental liquid rivulets. The liquid distribution over a one-dimensional array of capillaries is simulated and the basic Features of gas-liquid now in packed beds are demonstrated. With proper correspondence of hysteresis branches with nonuniformity of flow distribution assumed, the experimentally observed hysteresis in pressure drop, liquid holdup and mass transfer rate can be qualitatively simulated. Strenuous efforts are stilt required for further developing this model into a predictive tool for the evaluation of performance of packed-bed type devices.
