Download or read book Drag Reduction of Turbulent Flows by Additives written by A. Gyr and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drag Reduction of Turbulent Flows by Additives is the first treatment of the subject in book form. The treatment is extremely broad, ranging from physicochemical to hydromechanical aspects. The book shows how fibres, polymer molecules or surfactants at very dilute concentrations can reduce the drag of turbulent flow, leading to energy savings. The dilute solutions are considered in terms of the physical chemistry and rheology, and the properties of turbulent flows are presented in sufficient detail to explain the various interaction mechanisms. Audience: Those active in fundamental research on turbulence and those seeking to apply the effects described. Fluid mechanical engineers, rheologists, those interested in energy saving methods, or in any other application in which the flow rate in turbulent flow should be increased.

Available in PDF, EPUB and Kindle. Book excerpt: Five studies are presented in this publication: A comparison between the behaviour of polymer solutions and flow characteristics of linear elastico-viscous fluid models. The study shows that no linear model can predict consistently all the observed non-Newtonian phenomena of polymer solutions; Turbulent flow of dilute polymer solutions through an annulus. Experimental and theoretical results are presented; Measurements of the dynamic response of flowing polymer solutions with a vibrating torsional quartz crystal are presented. The dynamic elastico-viscous response is found to be independent of the flow characteristics and shear rates; Drag reduction in developing boundary layers by injection of polymer solutions. Reduction of local friction coefficients is of the order of 65 percent, however, energy losses in the injection region decrease the total drag reduction efficiency. Effect of the injection concentration and discharge, width of slot and mean stream velocity are found; Drag reduction and degradation tests of several polymer solutions are presented. (Author).

Download or read book Rheology of Drag Reducing Fluids written by Aroon Shenoy and published by Springer Nature. This book was released on 2020-03-25 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains theoretical derivations and presents expressions for fluid and convective turbulent flow of mildly elastic fluids in various internal and external flow situations involving different types of geometries, such as the smooth/rough circular pipes, annular ducts, curved tubes, vertical flat plates, and channels. Understanding the methodology of the analyses facilitates appreciation for the rationale used for deriving expressions of parameters relevant to the turbulent flow of mildly elastic fluids. This knowledge serves as a driving force for developing new ideas, investigating new situations, and extending theoretical analyses to other unexplored areas of the rheology of mildly elastic drag reducing fluids.The book suits a range of functions--it can be used to teach elective upper-level undergraduate or graduate courses for chemical engineers, material scientists, mechanical engineers, and polymer scientists; guide researchers unexposed to this alluring and interesting area of drag reduction; and serve as a reference to all who want to explore and expand the areas dealt with in this book.
