摘要: The usefulness of discrete element method simulation for studying fluidization nanoparticle agglomerates is explored. Nanoparticle were simulated by using solid particles equivalent sizes and densities. Validity the present was assessed through comparisons results experimental observations bed expansion, characteristic behaviour, dense-bed settling. then used to investigate initial expansion uniformity under particulate conditions. role inter-agglomerate interparticle force in examined. A stability analysis originally developed addressing transition from bubbling conventional predicting start fluidized beds agglomerates.
