Drag Reduction of Complex Mixtures discusses the concept of drag reduction phenomena in complex mixtures in internal and external flows that are shown experimentally by dividing flow patterns into three categories. The book is intended to support further experiments or analysis in drag reduction. As accurately modeling flow behavior with drag reduction is always complex, . 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 . This form of laminar drag reduction represents a relatively new area of research, where the laminar flow can be controlled by microscopic surface modifications, allowing fluid flows to slip over a wall. Laminar Drag Reduction brings information about some interesting phenomena related to fluid slippage on a highly water-repellent by: 1. Drag Reduction of Turbulent Flows by Additives is the first treatment of the subject in book form. Fluid mechanical engineers, rheologists, those interested in energy saving methods, or .
Description. Drag reducing agents can be broadly classified under the following four categories – Polymers, Solid-particle suspensions, Biological additives, and agents are made out of high molecular weight polymers or micellar systems. The polymers help with drag reduction by decreasing turbulence in the oil lines. This allows for oil to be pumped through at . The experimental results presented in this book show that frictional drag of a fluid alongside this hydrophobic wall decreases in comparison with fluid flow along a conventional wall or form of laminar drag reduction represents a relatively new area of research, where the laminar flow can be controlled by microscopic surface. Abstract. Nature has created ways of reducing drag in fluid flow, evident in the efficient movement of fish, dolphins, and sharks. The mucus secreted by fish reduces drag as they move through water, protects the fish from abrasion by making the fish slide across objects rather than scrape, and prevents disease by making the surface of the fish difficult for Cited by: 5. The Drag Reduction and Flow Control Special Interest Group (SIG) is one of the founding groups of ERCOFTAC Association when it was established in It has organised numerous specialised meetings - European Drag Reduction and Flow Control Meetings - on drag reduction and flow control so far, with the next meeting scheduled in September
This book explains theoretical derivations and presents expressions for fluid and convective flow of mildly elastic fluids in various internal and external flow situations involving different geometries: smooth/rough circular pipes, annular ducts, curved tubes, vertical flat plates, and channels. European Drag Reduction and Flow Control Meeting March , Haus der Kirche, Bad Herrenalb, GERMANY. ERCOFTAC Special Interest Group (SIG20) - Drag Reduction and Flow Control and the Institute of Fluid Mechanics (ISTM) of Karlsruhe Institute of Technology (KIT) are pleased to announce the next European Drag Reduction and Flow Control Meeting . 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. Nikolaos D. Katopodes, in Free-Surface Flow, Hele-Shaw Flow. Another interesting application of creeping flow arises when a viscous fluid is forced to pass between two parallel flat walls separated by a small distance problem is a generalization of the one-dimensional case discussed in section , and corresponds to an experimental apparatus used to .
