Abstract

A combination of Happel's free surface model and variational principles is used to obtain bounds on the drag offered by the creeping flow of a power law fluid past an assemblage of solid spheres. The theoretical predictions of the product of the Fanning friction factor ƒ and Reynolds number Re~p~ are in close agreement with available experimental data on non‐Newtonian flow through porous media. The product (ƒ Re~p~) reduces for the Newtonian case to that of Happel and Brenner.
