Identifying States in Shallow Vibrated Beds
Shallow particulate beds on surfaces vibrating at ca. 25 Hz and an amplitude of a few millimetres display several states, in order of increasing bed depth: two ‘Newtonian states’ in which freely bouncing particles obey simple New tonian mechanics; a ‘coherentexpanded (C-E) state’ in which particles move together in loosely organized packets to form a turbulent shallow layer; and a ‘coherent-con...
متن کاملUse of polyurea from urea for coating of urea granules.
A new type of controlled release fertilizers coated with polyurea was prepared. The granulated urea was firstly changed into a liquid urea by heating as the coating liquid. By spraying uniformly the urea was coated with the polyurea synthesized by the reaction of isocyanates with a liquid urea. The effects of different modifiers on N release characteristics of polyurea-coated urea (PCU) were st...
متن کاملExperimental analysis and visualization of spatiotemporal patterns in spouted fluidized beds.
A numerical characterization based on experimental data of the spouting regime in a two-dimensional fluidized bed is presented. The aspect ratio of the bed allowed for good visualization of the spouting and solids circulation as the spouting jet gas velocity was varied to highlight the visited bifurcation sequence. Digital video sequences were recorded and then preprocessed for numerical analys...

متن کاملApplicability of the spouting regime for drying of biomass wastes in conical spouted beds with a draft tube
The operating conditions in spouted bed regime of uniform beds consisting of different biomass wastes dry and wet have been studied to determine the applicability of conical spouted beds with a draft tube in the drying of biomass wastes. This experimental study has been carried out at room temperature and the effect of the solid humidity on the stability of beds of biomass wastes has been deter...
