Turbulent Pipe Flow of “Rod-Like” Polymer Solutions

In this study the drag reduction of an aqueous solution of a rigid “rod-like” polymer, scleroglucan, at a concentration of 0.01% w/w in a 100-mm diameter, 23-m long circular pipe-flow facility was experimentally investigated. Pressure-drop measurements were conducted via a differential pressure tran...
