The results of experimental investigation of elastic effects in the creeping flow of viscoelastic fluids through fixed beds of spherical and nonspherical particles are presented. A simple form of the corrective Deborah number function has been suggested enabling relations valid for the fixed bed flow of purely viscous fluids to be used for the estimation of pressure drop in the flow of viscoelastic fluids.
