Experimental 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 کاملModelling radiative heat transfer in packed beds
A comprehensive approach for modelling dependent radiative heat transfer in beds of large (geometric range) spherical particles is presented. Such a system of large spheres lies in the dependent range even for large porosities. We show that the dependent properties for a bed of opaque spheres can be obtained from their independent properties by scaling the optical thickness while leaving the al...
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...
متن کاملHeat Transfer Mechanisms in a Gas – Liquid-Solid Fluidized Beds
Three-Phase Fluidized Beds have found an important place in processing technology as Reactors. Gas-Liquid-Solid fluidization is considered in the present paper as operating bed of fluidized solid particles simultaneously with co-current upward flow of a continuous liquid phase and a gaseous phase dispersed in the form of bubbles. In the present study, the experimental work of the author on heat...
