“…On the other hand, cationic surfactants were examined in [91], which distinguishes between various cationic surfactants. The discussed cationic surfactants were CTAB (cetyltrimethylammonium bromide), CTAC (cetyltrimethylammonium chloride), and Arquad S-50 (oleytrimethylammonium chloride).…”

“…However, adding a temperature above 48 • C will reduce the drag reduction effect [95]. Regarding the Arquad S-50, the flow velocity is inversely proportional to CTAC and CTAB [91]. The friction factor decreases as the fluid velocity increases at a temperature of 18 • C. Cationic surfactants are useful when at an optimum temperature [91].…”

Reduction of fluid resistance using the rheological characteristics of a polymer-surfactant solvent is research that contains many aspects, such as the theory of the drag reduction process, historical journey, and ongoing current research development. Many studies have been conducted, but it is challenging to know all existing and new research threads. The present investigation was conducted using literature studies regarding drag reducing agents. This research will also discuss the characteristics of flowing fluids and their effects on the velocity profile with friction factor of flowing fluids in smooth circular straight pipe geometries based on experimental, theoretical approaches. It concludes with aspects of research conducted around reducing drag using drag reducing agents, ideas about innovations, structuring overlook in testing, and modification of the fluid flow state.
