摘要: Abstract The hydrodynamic structure of the grid zone, i.e. , region between bed bottom and jet top, was investigated by using semicylindrical fluidized beds having a transparent front wall. It found that in zone there were two different regions: lower named ‘jet stem’ where jets exist stably upper ‘bubble-forming’ region. effects particle diameter superficial gas velocity on heights these regions experimentally investigated. fraction bubble-forming whole height strongly dependent diameter.
