Fluidization deals with complex fluid-particle contacts in multiphase flow, and continuing efforts and progresses have been made in improving the fundamental understanding of hydrodynamics, heat/mass transfer phenomena in fluidized beds, leading to advanced modeling, design and scale-up of existing and emerging novel fluidized bed and other related multiphase reactors. We welcome all papers on recent progress in hydrodynamics, transport phenomena, reactor modeling and scaleup of novel and unconventional multiphase reactors, as well as the development of novel diagnostic and measuring techniques.
