摘要: Simple models, based on liquid-solid and gas-liquid interaction are proposed in order to model a flow trickle-bed reactors operating high regimes. Good results obtained, when the interactions modeled separately. Besides classical Ergun equation, simple of interactions, boundary layer is proposed. This approach relation which very close well-known liquid saturation correlation by Specchia Baldi (1977, Chem. Engng Sci.32, 515–523), might be its theoretical justification. The using drift-flux approach. different models tested against data bank about 1500 pressure drop measurements, established mainly Nancy research group. importance geometrical characteristics porous media their incomplete description emphasized. Finally predictive correlations proposed, compared literature correlations.
