The article reports on the results of the pressure drop measurements in dependence on the liquid volume flow rate in the creeping flow of viscoelastic aqueous polymer solutions through woven metal screens. The respective experiments were performed in a plastic cell of 50 mm inner diameter in which the tested screen had been placed. In such measurements, the six types of screens of different weaving were examined in the flow of nine various polymer solutions. In the flow, a strong elastic pressure drop excess manifests itself. By analysing the experimental data, it has been verified that the pressure drop excess can be evaluated using the corrective Deborah number function.
