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

The rich diversity of man-made complex fluids and naturally occurring biofluids is opening
up new opportunities for investigating their flow behavior and characterizing their …

We investigate theoretically the steady incompressible viscoelastic flow in a hyperbolic
contracting channel. The fluid viscoelasticity is modeled using the upper convected Maxwell …

The microfluidic flow is typically laminar due to the dominant viscous effects. At Reynolds
numbers far below 1 (Re≪ 1), the fluid inertia can be neglected. For the steady flow of …

We analyse the pressure-driven flow of the Oldroyd-B fluid in slowly varying arbitrarily
shaped, narrow channels and present a theoretical framework for calculating the …

Flow of an Oldroyd-B fluid in a slowly varying contraction: theoretical results for arbitrary
values of Deborah number in the ul Page 1 J. Fluid Mech. (2024), vol. 988, A10, doi:10.1017/jfm.2024.223 …

Micelles are formed by the self-assembly of surfactants in solutions. Wormlike micelles or
living polymers are a particularly interesting fluids because their long flexible cylindrical …

Rare-earth phosphors exhibit unique luminescence polarization features originating from
the anisotropic symmetry of the emitter ion's chemical environment. However, to take …

The rheological characterisation of liquids finds application in several fields ranging from
industrial production to the medical practice. Conventional rheometers are the gold standard …

We employ time-resolved flow velocimetry and birefringence imaging methods to study the
flow of a well-characterized shear-banding wormlike micellar solution around a novel glass …
