1. Interparticle forces

1.1 Demonstration of interparticle forces

By definition, the fluidized state is reached when the drag force exerted by the gas offsets the force of gravity. So it's easy to imagine that a fluidized bed will behave differently if cohesive forces are added between the particles.

Historically, a great deal of research has been carried out to characterize the fluidization of Class A particles. According to Geldart et al. ...
