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.

Turbulent drag reduction by additives has long been a hot researchtopic. This phenomenon is inherently associated with multifoldexpertise. Solutions of drag-reducing additives are usuallyviscoelastic fluids having complicated rheological properties.Exploring the characteristics of drag-reduced turbulent flows callsfor uniquely designed experimental and numerical simulationtechniques and elaborate theoretical considerations.

The addition of a minute amount of polymer or surfactant additive to a turbulent fluid flow can result in a large reduction in the frictional drag in pipes and channels. Over the past decades, numerous studies have been carried out on drag reducing additives (DRA). DRA have been successfully applied

Drag reduction is a remarkable ability to reduce the frictional resistance in the turbulent flow by adding a low concentration of certain additives, drag reducing additive agents (DRA). High costs of fluid transportation (such as pumping the liquids into the pipelines) in production processes has made drag reduction subject of
