Abstract
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
