A small amount of polymer additives can cause substantial reduction in the energy
dissipation and friction loss of turbulent flow. The problem of polymer-induced drag …

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 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 …

This review highlights the profound and unexpected ways in which viscosity varying in
space and time can affect flow. The most striking manifestations are through alterations of …

Turbulence is ubiquitous in nature, yet even for the case of ordinary Newtonian fluids like
water, our understanding of this phenomenon is limited. Many liquids of practical importance …

Turbulent drag reduction by polymer additives in a channel is investigated using direct
numerical simulation. The dilute polymer solution is expressed with an Oldroyd-B model that …

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 …

The drag of turbulent flows can be drastically decreased by adding small amounts of high
molecular weight polymers. While drag reduction initially increases with polymer …

Pharmacovigilance is, in essence, the process of monitoring the everyday use of medicines
to identify previously unrecognized adverse drug reactions thereby assessing their …

Friction reducers (FRs) play a vital role in large-displacement shale hydraulic fracturing. This
paper reviews the drag reduction (DR) mechanism of FRs, its development and application …
