Abstract

The effects of taper on the steady-state expansion characteristics of a homogeneous fluidized bed are examined theoretically and experimentally. It is shown that secondary factors that might be thought to influence the expansion (fluid accelerational effects including added mass and particle phase elasticity) are unlikely to be of significance in practical situations.
