The mechanism of drag reducing surfactant is introduced. Many factors influencing the effectiveness of drag reducing surfactant are addressed, such as surfactant, counterion, concentration, diameter of circulating systems, temperature and velocity of the fluid, and ions inside the recirculation systems. The relationship between drag reduction and heat transfer ability is discussed, and methods of improving the efficiency of heat transfer in the recirculation systems containing the drag reducing surfactant are also described. Common characteristics of drag reducing surfactant are summarized. Finally,the development trend of drag reducing surfactant is indicated. 35 references are cited.
