Polymer-Surfactants Physiochemical Interaction for Enhancing the Flow and Mechanical Characteristics of Polymeric Drag Reducing Agent by Oluwasoga, Akindoyo Edward, Abdulbari, Hayder A.

“…Frictional pressure in turbulent flows attributed to pipes and eddies interaction are great challenges that increase coast of transporting liquids in pipelines since high rate of energy is consumed, often prevented in many ways such as polymeric additives introduced in low concentrations, but degrade over critical shear stress for their high molecular weight and long chain, surfactants are introduced to form complexes with the polymer to generating threadlike self repairing micelles if cationic surfactants with organic salts, could yield greater drag reduction since the ions are capable of entangling strongly to the micellar structures formed at low concentration (1mM). …”
