Toms Effect as Influenced by the Glass Capillary Length and Diameter

Abstract

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].
