Complex fluids exist in nature and are continually engineered for specific applications
involving the addition of macromolecules to a solvent, among other means. This imparts …

A viscous solvent laminar flow may be strongly modified by the addition of a tiny amount of
long polymer molecules, resulting in a chaotic flow called elastic turbulence (ET). ET is …

Viscoelastic fluids are a common subclass of rheologically complex materials that are
encountered in diverse fields from biology to polymer processing. Often the flows of …

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 …

A book of 420 pages with the simple title Rheology, written in 2006, that's intriguing! After an
introduction and a literature survey (citing many of the classical works on fluid mechanics …

The Oldroyd-B model has been used extensively to predict a host of instabilities in shearing
flows of viscoelastic fluids, often realized experimentally using polymer solutions. The …

Polymer solutions are frequently used in enhanced oil recovery and groundwater
remediation to improve the recovery of trapped nonaqueous fluids. However, applications …

Microorganisms navigate through complex environments such as biofilms and mucosal
tissues and tracts. To understand the effect of a complex medium upon their locomotion, we …

The development and growth of microfluidics has stimulated interest in the behaviour of
complex liquids in micro-scale geometries and provided a rich platform for rheometric …

It is presently believed that flows of viscoelastic polymer solutions in geometries such as a
straight pipe or channel are linearly stable. Here we present experimental evidence that …
