The aim of this review was to summarize information and scientific data from the literature
dedicated to the fate of polyacrylamide (PAM)-based flocculants in hydrosystems …

The efficiency of drag reduction (DR) is known to be impaired by mechanical scission of
molecules, which is a great obstacle to the practical use of flexible polymeric drag reducers …

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 …

Polymer-induced drag reducing flow has been investigated for over 60 years. One reason
for this is that the drag reducers in flow systems have been successfully applied and …

Friction drag is a nonnegligible matter when relative motion happens between solid and
liquid phase, which brings many inconveniences in ship navigation, fluid transportation …

The relation between the drag reduction (DR) performance of several water-soluble
polymers and their viscoelastic properties was investigated. Polymers with a flexible …

Polymer-induced drag reduction has yielded great potential benefits for industrial processes
after more than 70 years of research. However, the limitation of low shear stability has …

Water-soluble polymers with high molecular weights are known to decrease the frictional
drag in turbulent flow very effectively at concentrations of tens or hundreds of ppm. This drag …

We study the ability of diutan gum (DG), a polysaccharide that belongs to a class called
sphingans, to improve drag reduction (DR) in turbulent flows. This new drag reducer is very …

This work provides a more favorable implementation of synergistic drag reduction strategies
based on molecular simulations of the strength of polymer-surfactant interactions. The …
