“…1) The fact that the T = f(c) dependences are similar has been noted by the majority of researchers [1,11]. With increasing polymer concentration, T initially tends to increase and then, upon achieving certain optimal concentration, approaches a constant value or begins to smoothly decrease.…”

The degree of reduction of the hydraulic resistance was studied as influenced by the concentration of the anionic copolymer of acrylamide, geometric parameters of the contour, and turbulent flow velocity.High-speed transportation of oil-containing dispersed systems via main pipelines with the use of polymeric additives, such as, e.g., polyolefins, for reducing the hydraulic resistance of turbulent oil streams (Toms effect) has recently demonstrated a high economic efficiency [13 4].

“…The conclusion that there exists an optimal polymer concentration c opt in solution was also made by Manzhai et al [55] in a study of the hydrodynamic MYAGCHENKOV, CHICHKANOV efficiency of polyisoprene samples in a turbulent flow of dry oil. On carrying out a set of experiments with polyisoprene samples of varied molecular weight introduced into and oil-containing dispersed system, the authors revealed a dependence of the optimal concentration on the molecular weight of the polymer additive.…”
