Chiral Lemniscate Formation in Magnetic Field Controlled Topological Fluid Flows
Small, Volume 21, Issue 20, May 19, 2025.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 ...

Experimental investigation of laminar turbulent intermittency in pipe flow
, 2011 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 ...

Bubble dissolution in Taylor–Couette flow
Journal of Fluid MechanicsWe perform direct numerical simulations of soluble bubbles dissolving in a Taylor–Couette (TC) flow reactor with a radius ratio of $\eta =0.5$ and Reynolds number in the range $0 \leq Re \leq 5000$ , which covers the main regimes of this flow configuration, up to fully turbulent Taylor vortex flow.

Anomalous Shear Stress Variation in Wet Granular Medium: Implications for Landslide Lateral Faults
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.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.
PLoS ONE, 2019 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
, 2000 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 ...
