Abstract
The flow through a packed bed was evaluated experimentally as a simple qualitative method for the estimation of the degree of elasticity in dilute polymer solutions. The pressure drops for the dilute polymer solutions (Separan and Polyox) were found to be about 2-9 times higher than those for Newtonian fluids with identical viscosities. Plots of relative pressure drop show distinct maxima for different polymer concentrations. Solutions of higher Separan concentrations, believed to exhibit more pronounced elastic effects, result in pressure peaks at lower flow velocities or Reynolds numbers. The effects of solution aging and polymer degradation were also studied.
