THE EFFECT OF SURFACTANT AND HIGH MOLECULAR WEIGHT POLYMER ADDITION ON PRESSURE DROP REDUCTION IN PIPE FLOW

Abstract The main aim of this paper is to present a possibility to enhance the drag reduction effect in straight pipe flow by the simultaneous addition to the transported liquid of a small amount of high molecular weight polymers and surfactants. Qualitative analysis of the polymer-micellar additive influence on the shape and character of flow resistance curves has been performed. Also multicomponent polymer-micellar solution flow resistance curves were compared with appropriate single additive polymer or surfactant solution flow resistance curves. The experimental data shows that, for polymer...
