Análise Fluidodinâmica de Partículas Cilíndricas em Leito Fluidizado com Variação da Razão de Aspecto

Abstract

The minimum fluid velocity of the particles is a hydrodynamic parameter that strongly influences the behavior in fluidized bed reactor designs. Most of the academic works use as one of the main parameters in their correlations the sphericity. Other studies state that the aspect ratio greatly influences the minimum fluidization velocity. Using a fluidized bed reactor, cylindrical bamboo particles with aspects ratios of 2, 4 and 6 were fluidized. The results of the minimum fluidization velocities were compared with other authors, where three were close enough within a range of variation of 20% of the values obtained in the experiments. A new correlation was proposed by varying the aspect ratio where the values of the minimum fluidization were very close to that of the experimental one.
