A model for pressure drop and liquid saturation in gas-liquid cocurrent upflow through packed beds
A macroscopic model for pressure drop and liquid saturation in cocurrent gas-liquid upflow through packed beds was proposed. The three model parameters: two accounting for the effect of reduction in cross sectional area available for each phase due to the presence of the other, the third accounting for the effect of bubble formation were evaluated from the experimental data of the earlier investigation. The validity of the model for predicting the pressure drop was tested with an independent data reported in literature.
