Pressure drop for the slow flow of dilatant fluids through a fixed bed of spherical particles

The equations of motion in conjunction with the free surface cell model have been solved numerically for the creeping flow of dilatant fluids through a fixed bed of spheres. The effect of the flow behaviour index (1 ≤ n ≤ 2) on the individual as well as the total drag coefficients is elucidated. Finally, the theoretical predictions have been validated using the scant experimental results available in the literature. Copyright © 1994 Canadian Society for Chemical Engineering
