“…Physico-chemical experiments have established that surfactant molecules in solution at rest assemble into micelles with shapes like spheres, rods or even blades [4]. The situation changes and becomes more complicated when the surfactant molecules are dissolved in water.…”

In this paper the behavior of an aqueous surfactant solution in a rotational Couette viscometer is investigated. It is shown that this behavior depends strongly upon time, upon the way in which the flow curve is obtained (with increasing or decreasing shear rate), upon the temperature, and upon the concentration of the solution. Furthermore, the results also reveal a pronounced dependence upon the size of the actual measuring system used. It is shown that the slip-velocity concept is not applicable to explain this dependence.

“…The effect on drag reduction can be seen based on the shape of the component ions and the macromolecular structure of each type. The micellar type has been demonstrated in studies [47], where the shape of the micellar solution affects the inhibition reducing ability supported by high solution concentrations [48]. There are studies that provide specific differences between micellar shapes (spherical [45], rod [49], cylindrical [49]) and their drag reduction effect [45,49], proving that micellar variations can cause drag reduction effects [27] for surfactants.…”

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.

“…An idea of the morphological parameters for micellar systems, for the conditions of maximum drag reduction activity, can be obtained from Savins [207] who estimated the same using the information of Pilpel [293]. The shape of the micelles of a complex soap causing the Toms effect has been discussed in detail very recently by Myska and Simeckova [294] who confirm the existence of fibrillous structure.…”

A state-of-the-art review on drag reduction has been presented in order to bring out some important aspects of the drag reduction phenomenon and its potential for practical use. The review is biased towards micellar systems and discusses in detail the morphological differences between drag reducing polymeric and micellar systems. Work relating to polymeric systems has not been dealt in detail as it has been the subject of earlier reviews. Studies relating to biological additives as well as suspensions have been briefly mentioned without detailed discussion as their potential for practical use presently appears to be limited.
