摘要: Previous work on the rise of a swarm bubbles in non-Newtonian media has been reviewed. Variational principles have combined with Happel free surface cell model to obtain upper and lower bounds velocities rising slowly through power law liquids. The predictions presented herein encompass wide ranges gas holdup shear-thinning behaviour. On fait une etude de la litterature sur montee d'un agglomerat bulles en milieu non newtonien. Des principes varationnels ont ete combines un modele cellule libre dans le but d'obtenir des limites superieures et inferieures vitesse d'agglomeration montant lentement liquides type loi puissance. De ce fait, les presentees couvrent large gamme retention gaz comportement rheofluidisant.
