ABSTRACT

The objective of this work is to evaluate the flow of polymer solutions through porous media. Flow tests were performed with different polymeric solutions through consolidated inert porous media at large pressure differentials (high deformation rates). Experimental results indicate expressive deviation from Darcy’s law. The next step was to validate alternative expressions for resistive forces that contemplate the effects of the first normal stress difference, as defined by Noll (1958). Based on such expressions, regions of viscosity-governed flows, elasticity-governed flows, and mixed flows were identified.
