The flow ofnon-Newtonian purely viscous fluids through packed beds of different structures has been investigated and a model of calculation of the pressure drop is proposed. This model takes into account the structural parameters of the porous medium: the tortuosity T, the dynamic specific surface a
## 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 Ζ and Reynolds nu
