A comprehensive,predictive two-channel model has been proposed to describe the core/annular internal recirculation flow structure in gas-solid cocurrent upflow system. The flow patternshave been determined based on minimizing the available interaction between gas and particles andthe prineiple of conservation of mass and momentum in the system.Computational results,such as those of the core region radius,voidage,gas and particlevelocities,gas and particle fluxes and their axial distributions in the...

A comprehensive,predictive two-channel model has been proposed to describe the core/annular internal recirculation flow structure in gas-solid cocurrent upflow system. The flow patternshave been determined based on minimizing the available interaction between gas and particles andthe prineiple of conservation of mass and momentum in the system.Computational results,such as those of the core region radius,voidage,gas and particlevelocities,gas and particle fluxes and their axial distributions in the core and annular channels,arequite rational and in agreement with experimental results.The proposed model can also be used topredict the drag coefficients and backmixing in two channels,and the mass exchange between coreand annular regions.
