摘要：

The boundary condition,zero solids pressure at the top of a particle bed of maximum spoutable height,Hm,is shown to eliminate any resort to empiricism in the derivation of the fluid velocity in the annulus of a spouted bed for which both viscous and inertial effects are taken into account.The same boundary condition fails when applied to a spouted bed for which the bed height H<Hm,especially when H<0.8Hm.
