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

Abstract Generalised Newtonian Fluid (GNF) models which assume that the viscosity of a
non-Newtonian fluid can be modelled inelastically as a time-independent, ie instantaneous …

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 …

Increasing flooding-solution viscosity with polymers provides a favorable mobility ratio
compared with brine flooding and hence improves volumetric sweep efficiency. Flooding …

Effective mixing in microscale systems encounters difficulties due to the inherently low
Reynolds numbers. This investigation delves into harnessing elastic instability and elastic …

Viscoelastic flows through porous media become unstable and chaotic beyond critical flow
conditions, impacting widespread industrial and biological processes such as enhanced oil …

Complex and active fluids find broad applications in flows through porous materials.
Nontrivial rheology can couple to porous microstructure leading to surprising flow patterns …

Viscoelastic polymer solutions exhibit a variety of flow instabilities and in particular, in mixed
shear and extensional flow, elastic turbulence. Coincident with the transition to turbulence is …

Many energy, environmental, industrial, and microfluidic processes rely on the flow of
polymer solutions through porous media. Unexpectedly, the macroscopic flow resistance …

Single-phase flows of viscoelastic polymer solutions in both microfluidic devices and rock
cores exhibit apparent flow thickening. We demonstrate that this thickening occurs above a …
