This article provides a review of recent progress in understanding and predicting polymer
drag reduction (DR) in turbulent wall-bounded shear flows. The reduction in turbulent friction …

The use of sedimentary structures as indicators of flow and sediment morphodynamics in
ancient sediments lies at the very heart of sedimentology, and allows reconstruction of …

Modern production methods and environmental constraints demand chemical solutions. And
as oilfields age, the need for chemicals to ensure steady production increases. Production …

The third edition of this besteller covers the latest advancements in this rapidly growing field.
Focusing on analyses and critical evaluation of the subject, this new edition reviews the …

It is well known that the drag in a turbulent flow of a polymer solution is significantly reduced
compared to Newtonian flow. Here we consider this phenomenon by means of a direct …

This book provides a general introduction to the topic of turbulent flows. Apart from classical
topics in turbulence, attention is also paid to modern topics. After studying this work, the …

Addition of a small amount of very large polymer molecules or micelle-forming surfactants to
a liquid can dramatically reduce the energy dissipation it exhibits in the turbulent flow …

It has become a well-known fact that finding sustainable solutions to the unavoidable high
pressure losses accompanying pipeline flows to increase the pumping capacity without …

The interactions between surfactants and a drag-reducing polymer were investigated at a
low polymer concentration of 500 ppm, using measurements of the rheology and surface …

The flow of fluids in channels, pipes, or ducts, as in any other wall-bounded flow (like water
along the hulls of ships or air on airplanes) is hindered by a drag, which increases manyfold …
