The flow between concentric cylinders is routinely used in soft matter studies. In many cases,
the purpose of the setup is rheometric: the idea is to relate macroscopic changes in material …

Since the seminal work of Taylor in 1923, Taylor–Couette (TC) flow has served as a
paradigm to study hydrodynamic instabilities and bifurcation phenomena. Transitions of …

Solutions of long, flexible polymer molecules are complex fluids that simultaneously exhibit
fluid-like and solid-like behavior. When subjected to an external flow, dilute polymer …

The Oldroyd-B fluid has become the starting point for almost all complex flow calculations
and analysis involving the behavior of dilute polymer solutions. The reasons for this are …

The flow physics of inertio-elastic turbulent Taylor–Couette flow for a radius ratio of
considered. In fact, these vortices develop herringbone streaks near the inner wall that have …

Shear-banding is ubiquitous in complex fluids. It is related to the organization of the flow into
macroscopic bands bearing different viscosities and local shear rates and stacked along the …

We study Taylor–Couette flow of a glycerol–water mixture containing a wide range of
concentration (0–2000 ppm) of xanthan gum, which induces both shear-thinning and …

Direct numerical simulation (DNS) of elastically induced turbulent flows has posed great
challenges to researchers engaged in develo** first-principle models and simulations that …

The critical modes of the instabilities of viscoelastic Taylor–Couette flow are investigated
using both experiments and linear stability analysis when only one cylinder rotates and the …

Direct numerical simulations in a wide-gap turbulent viscoelastic Taylor–Couette flow in the
Reynolds number (R e) range of 1500 to 8000 reveals the existence of a maximum drag …
