Rheology of Friction-Reducing Polymer Solutions

Abstract

Stress decay characteristics of concentrated (0.14% - 1.03%) polyethylene oxide solutions were measured. Apparent viscosity loses of up to 50% were recorded at 30C. Shear rates ranged up to 1370/sec. Limiting viscosities were found to be relatively independent of solution history. Disk flow was used to investigate the phenomenon of turbulent drag reduction and subsequent mechanical degradation of dilute aqueous solutions of polyethylene oxide. The relationship of drag reduction and degradation to the molecular weight, solution concentration and temperature was investigated. Reduced viscosity measurements (which are a measure of molecular weight of polymer) were carried out directly on the dilute solutions tested.
