Estimation of the Dynamic Parameters of Mono
and Bicomponent Granular Particles Beds Fluidization

Abstract:

Experimental research of dynamic structure of the granular beds of clay, steel and clay- metallic particles mixtures aimed to determine the operating fluidization parameters, to identify optimal conditions for contacting gas - granular material and to intensify mass transfer operations with minimum energy consumption. The main dynamic parameters of fluidization were experimentally determined: the minimum fluidization velocity of pure materials used, the minimum fluidization velocity of mixtures clay- metallic particles (steel) and the minimum pressure drop, depending on the geometric simplex L0/D and the concentration of different particles in the mixture. Applying regression analysis of experimental data were proposed empirical relationships using the operational parameters. Keywords: dynamic parameters, fluidization, regression analysis
