Available in PDF, EPUB and Kindle. Book excerpt: Turbulent drag reduction by additives has long been a hot research topic. This phenomenon is inherently associated with multifold expertise. Solutions of drag-reducing additives are usually viscoelastic fluids having complicated rheological properties. Exploring the characteristics of drag-reduced turbulent flows calls for uniquely designed experimental and numerical simulation techniques and elaborate theoretical considerations. Pertinently understanding the turbulent drag reduction mechanism necessities mastering the fundamentals of turbulence and establishing a proper relationship between turbulence and the rheological properties induced by additives. Promoting the applications of the drag reduction phenomenon requires the knowledge from different fields such as chemical engineering, mechanical engineering, municipal engineering, and so on. This book gives a thorough elucidation of the turbulence characteristics and rheological behaviors, theories, special techniques and application issues for drag-reducing flows by surfactant additives based on the state-of-the-art of scientific research results through the latest experimental studies, numerical simulations and theoretical analyses. Covers turbulent drag reduction, heat transfer reduction, complex rheology and the real-world applications of drag reduction Introduces advanced testing techniques, such as PIV, LDA, and their applications in current experiments, illustrated with multiple diagrams and equations Real-world examples of the topic’s increasingly important industrial applications enable readers to implement cost- and energy-saving measures Explains the tools before presenting the research results, to give readers coverage of the subject from both theoretical and experimental viewpoints Consolidates interdisciplinary information on turbulent drag reduction by additives Turbulent Drag Reduction by Surfactant Additives is geared for researchers, graduate students, and engineers in the fields of Fluid Mechanics, Mechanical Engineering, Turbulence, Chemical Engineering, Municipal Engineering.

Book Synopsis Rheology of Drag Reducing Fluids by : Aroon Shenoy
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.
Book Synopsis Investigation of Relationships Among Microstructure, Rheology, Drag Reduction and Heat Transfer of Drag Reducing Surfactant Solutions by : Yunying Qi
Download or read book Investigation of Relationships Among Microstructure, Rheology, Drag Reduction and Heat Transfer of Drag Reducing Surfactant Solutions written by Yunying Qi and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Drag reducing (DR) surfactant solutions can reduce pumping energy requirements in district heating and cooling (DHC) systems by 30-60%. To enhance the heat transfer ability of DR surfactant solutions, three methods were investigated. Fluted tube-in-tube heat exchangers and installing destructive devices at heat exchanger entrances were found to be very effective with moderate pressure drop penalties. The former is good for new DHC systems while the latter is ideal for existing DHC systems. Ultrasonic energy break up surfactant microstructures and enhance their heat transfer ability was effective for viscoelastic drag reducing surfactant solutions. The destructive devices and ultrasonic energy temporarily destroy the surfactant microstructure which enhances heat transfer. The microstructure recovers quickly and the solution regains its DR ability downstream of the exchanger. Unsaturated hydrocarbon chains with cis and trans configurations with different counterion/surfactant ratios influence the effective DR temperature range of cationic surfactant solutions, their shear degradation, their rheological behavior and their microstructures. Shearing effects on the microstructures of different DR surfactant solutions were studied using SANS. Surfactant microstructures aligned along the flow direction under shear. However, the critical shear rate for the initiation of alignment depends on surfactant microstructure. Differences and their relation to rheological properties and DR abilities are discussed. Shear induced structures (SIS) are accompanied by first normal stress difference (N1). Non-viscoelastic DR systems do not show SIS and N1. Threadlike micelle structures appear to be present in all DR surfactant solutions under shear, however. While some DR surfactant solutions have low extensional/shear viscosity ratios at extensional rates

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.

Book Synopsis Drag Reduction and Shear Degradation of Dilute Polymer Solutions as Measured by a Rotating Disk by : T. T. Huang
Download or read book Drag Reduction and Shear Degradation of Dilute Polymer Solutions as Measured by a Rotating Disk written by T. T. Huang and published by . This book was released on 1972 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A saturated drag-reduction line for dilute polymer solutions is derived for a rotating disk from new velocity-similarity laws. Drag reduction measured by a rotating disk is found to have three domains--oversaturated, optimal and undersaturated. At a given boundary-layer thickness and wall-shear stress, the drag-reduction increases with increasing concentration in the undersaturated domain, and the drag reduction does not increase with increasing concentration in the oversaturated domain. The boundary between the two domains is the optimal drag reduction, which is determined by the type of polymer and its concentration and a Reynolds number based on shear velocity and disk radius or boundary-layer thickness.

Book Synopsis Rheology - Volume II by : Crispulo Gallegos
Download or read book Rheology - Volume II written by Crispulo Gallegos and published by EOLSS Publications. This book was released on 2010-11-30 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rheology is a component of Encyclopedia of Chemical Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. Rheology is the study of the flow of matter. It is classified as a physics discipline and focuses on substances that do not maintain a constant viscosity or state of flow. That can involve liquids, soft solids and solids that are under conditions that cause them to flow. It applies to substances which have a complex molecular structure, such as muds, sludges, suspensions, polymers and other glass formers, as well as many foods and additives, bodily fluids and other biological materials. The theme on Rheology focuses on five main areas, namely, basic concepts of rheology; rheometry; rheological materials, rheological processes and theoretical rheology. Of course, many of the chapters contain material from more than one general area. Rheology is an interdisciplinary subject which embraces many aspects of mathematics, physics, chemistry, engineering and biology. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
