Abstract
Happel's free surface cell model has been combined with the equations of continuity and motion for the creeping motion of an ensemble of spherical bubbles through a generalized Newtonian fluid. The resultant equations have been solved approximately, using the variational principles, and upper and lower bounds to the drag force experienced by a swarm of bubbles have been obtained. Wide ranges of gas contents and non-Newtonian fluid parameters have been covered in this study. A method for estimating the rise velocity of a swarm of bubbles is also presented.
