摘要：

A simple model based on extension of the Blake-Kozeny equation to binary solid systems is developed to describe confined fluidization of fine particles. Pressure drop, minimum fluidization velocity and expansion characteristics have been determined for beds of glass ballotini fluidized within a fixed bed of coarse spheres. Good agreement between experimental and model results is found over a wide range of gas velocities. © 1990.
