Flow of polymer solutions through porous media

The flow of polymer solutions through porous medias has been investigated at different temperatures (278, 283, 288, 293, 298, and 303 K) and flow rates (from 0.659×10 -6 to 22.29×10 -6 m 3 /s). The ranges of shear rates and pressure drops were 10.8-692.5 s -1 and 0.414×10 5 to 2.72×10 5 Pa, respectively. Three different kinds of polymers (polyacrylamide, 1000 ppm concentration) were used in a 100-mm column packed with 2-mm particle diameter glass beads. Two types of modifications for Darcy's law were tested and discussed in the form of modified friction factor-Reynolds number correlations. First, the modified Blake-Kozeny equation for the flow of power law fluids through porous media was tested experimentally; second, a viscosity-temperature-shear rate correlation was developed and applied in the Blake-Kozeny equation for the flow of Newtonian fluids through porous media
