Computational and Experimental Study of Drying of Disperse Materials in a Circulating Fluidized Bed

Resumo

A mathematical model based on Markov chain theory is used to describe generation of mass fluxes when drying a material in a circulating fluidized bed. Experimental determination of the mass fluxes was the basis for tracking movement of a labeled particle. The predictive capability of the model was tested by comparing the calculations and the experimental data. We show the correlation between the circulation ratio and the moisture content of the material.
