NUMERICAL SIMULATION OF GAS FLUIDIZATION OF MIXTURES OF COHESIVE AND COHESIONLESS POWDERS

摘要

This paper presents a study of the effect of cohesionless particles on gas fluidization of cohesive powders using a Combined Continuum and Discrete Model. It is shown that by adding sufficient amount of cohesionless particles, sustainable fluidization can be achieved for cohesive powders which are difficult to fluidize by normal means.
