A centrifugal technique for separating molten polymer blends is investigated computationally. In a rotating cylinder, the components of mixtures of LDPE (Low‐Density Poly(Ethylene)) and PET (Poly(Ethylene) Terephthalate) are separated due to centrifugal forces due to the different component densities.

On the Onset of Taylor Vortices in Finite-Length Cavity Subject to a Radial Oscillation Motion
Taylor- Couette flow (TCF) is an important template for studying various mechanisms of the laminar-turbulent transition of rotating fluid in enclosed cavity.

Chiral Lemniscate Formation in Magnetic Field Controlled Topological Fluid Flows
The inner core of typhoon‐like fluid flow in a vortex fluidic device twists toroids of rapidly formed bundles of single‐walled carbon nanotubes into stable chiral lemniscates (figure 8s), predominantly as the R‐ or S‐structures, for an inclined tube rapidly rotating clockwise or counterclockwise, in a way that is impacted the Earth's magnetic field ...

NUMERICAL EXPLORATION OF VISCOUS FLOW REGIMES: INSIGHTS FROM POISEUILLE, COUETTE AND TAYLOR-COUETTE FLOWS [PDF]
We present a numerical study for Poiseuille and Couette as well as Taylor- Couette swirling flows. The governing equations of momentum and energy are transformed into coupled and nonlinear ordinary differential equations using similarity transformation ...

Experimental investigation of laminar turbulent intermittency in pipe flow
In shear flows turbulence first occurs in the form of localized structures (puffs/spots) surrounded by laminar fluid. We here investigate such spatially intermittent flows in a pipe experiment showing that turbulent puffs have a well defined interaction ...

Anomalous Shear Stress Variation in Wet Granular Medium: Implications for Landslide Lateral Faults
Abstract Landslide assessments typically focus on the mechanical properties of the basal shear zone, but lateral faults are frequently overlooked, possibly due to their lower normal stresses and variably saturated conditions. Using double‐cylinder shear experiments on wet granular systems as analogs for landslide lateral faults, we observe anomalous ...

Experimental investigation of Taylor-Couette-Poiseuille flow at low Taylor and Reynolds numbers.
Flow patterns of a Taylor-Couette-Poiseuille flow were studied at low axial Reynolds and rotational Taylor numbers (Re ≤ 10.5, Ta ≤ 319). The radius ratio of the inner and outer cylinders was 0.804 and the ratio of the length of the annulus to the gap ...

Transition from the Couette-Taylor system to the plane Couette system
We discuss the flow between concentric rotating cylinders in the limit of large radii where the system approaches plane Couette flow. We discuss how in this limit the linear instability that leads to the formation of Taylor vortices is lost and how the ...
