Fine-scale mixing in a gas-fluidized bed of fine particles

Probabilistic modeling of particle movement through a gravity separator

“…There are a number of aignificant differencea between the bed mechanica of a chemical reactor and the bed mechanics of a gravity der Waal* forces, capillary forces, and electrostatic forces can be important (Donsi and Massimilla, 1974;Rietema and Mutsers, 1974). Some researchers have attempted to use gas diffusion models to describe particle movement in gasfluidized beds (Buevich et al, 1980). Baile (1965) notes that some researchers consider the diffusion model to be invalid.…”
