Comparative analysis of drag reduction flow efficiency through the use of surfactants and high molecular polymer additives
Languages of publication
A comparative analysis of drag reduction efficiency through the use of surfactants and high molecular polymer additives has been performed. Results document that for polymer micellar solutions, the stable transitional zone between the laminar flow and the turbulent flow becomes extended towards higher Reynolds number values. The existence of a third extended drag reduction zone in the turbulent range of flow is also observed. It follows that the analysed polymer-micellar solutions combine and intensify positive features of their purely polymer and micellar analogues providing a more efficient drag reduction effect in wider range of flow.
