Abstract

A study on the flow of power-law fluids through a multi-particle system including both fixed bed and fluidized bed is presented. Equations for the pressure drop, the minimum fluidization velocity, and the bed expansion are obtained by extending the Blake-Kozeny's equation for the pressure drop through packed beds to power-law fluids. Bed expansion equations are also obtained by extending the Richard-son-Zaki's theory for the drag force in a multiparticle suspension to power-law fluids. These equations are compared with experimental data. On presente une etude de l'ecoulement des fluides d'entrainement dans un systeme a particules multiples forme a la fois de lits fixes et fluidises. On obtient des equations qui ont trait a la chute de pression a la velocite minimum de fluidisation et a l'expansion des lits, en etendant a des fluides d'entrainement l'equation de Blake-Kozeny relative a la chute de pression dans des lits garnis. On obtient egalement des equations pour l'expansion des lits en etendant a des fluides d'entrainement la theorie de Richardson-Zaki relativement a la force de trainee dans une suspension de particules multiples. On compare les dites equations avec des donnees experimentales.
