摘要：

Theory is developed to allow estimation of the particle to particle cohesive force from pressure drop versus expansion data of packed vibrated beds of very fine particles subject to a gentle upflow of gas. A consequence of this analysis is a prediction of the Geldart C/A transition which is then compared with other estimates from the literature.
