Drag Reduction by a Polymeric Aluminium Soap

Nature Physical Science volume 230, pages 152–153 (1971)Cite this article

Abstract

THE pressure drop per unit length of pipe during the turbulent flow of liquids is reduced by certain additives. Most such “drag-reducing” or “friction-reducing” agents are polymers of very high molecular weight1–3. In water, poly(ethylene oxide) at a concentration of ten parts per million can reduce the pressure for a given flow rate to a fifth of that required for water alone1,4. Suspensions may show drag reduction. Some soap or soap-complex solutions also show the phenomenon2,3.
