Pressure drop in vertical transport of solids was calculated using four hydrodynamic models previously proposed. The calculations were done using literature correlations of friction factors. Three of the models predict a minimum in pressure drop vs. superficial gas velocity. The three models - a relative velocity model, a model with pressure drop in the gas and solid phases, and a model with a pressure drop in the gas phase only - predict a choking behavior associated with flow reversal of particles. The relative velocity model compares well with Zenz's experimental data with a fixed inlet volume fraction.
