摘要
Part I: Kunii and Levenspiel proposed a flow model to represent the complex phenomena occurring in the freeboard above a fluidized bed. A somewhat more. The key parameter emerging from this model is the decay constant for the fall off of bulk density of solids with height in the freeboard. Values for th. Part II: Viewing the fast fluidized column as having a lower region of approximately constant bulk density and an upper region wherein the bulk density. An example of a design calculation shows how the fast fluidized system responds to changes in operating variables. More importantly, it makes clear wha. © 1990.
