摘要：
A one-dimensional analysis of the hydrodynamics of circulating fluidized bed risers is performed following brand new mass and momentum balances for a gas–solids flow that the author has recently proposed. This analysis also includes a characteristic slip velocity between the phases derived from classical particle mechanics (the single particle equation). The predictions of the pressure drop and the solids holdup axial profiles, and the dense bed height are successfully compared with a rather limited amount of data.
