Turbulent Flow Drag-Reduction by Dilute Poly(Ethylene Oxide) Solutions in Capillary Tubes.
Abstract
The study was initiated to investigate turbulent flow drag-reduction by dilute poly(ethylene oxide) solutions in capillary tubes and thereby elucidate the mechanism of drag-reduction through interpretation of the experimental results. Flow through capillary tubes was chosen as a means to (1) obtain a large ratio of solid surface area to fluid volume, and (2) obtain high shear stresses at low Reynolds numbers. This allowed investigation of surface effects and polymer degradation as a function of a number of variables which are known to influence drag-reduction. (Author)
