Spectral method for identification of flow regimes in a Couette-Taylor annular flow [PDF]

E3S Web of Conferences
The paper presents a study of flow structure in an annular flow of the Couette-Taylor system, employing spectral analysis of moment of resistance and radial dynamic pressure pulsations. Experiments were conducted on a model featuring a single annular gap,

Aggregation of silica nanoparticles in concentrated suspensions under turbulent, shear and extensional flows. [PDF]

, 2013
The production of nanoparticles in concentrated suspensions requires strict control of the stability of the systems which are strongly influenced by the physico-chemical properties and the hydrodynamic conditions they are placed in. This study deals with

Elastic turbulence in shear banding wormlike micelles

, 2010
We study the dynamics of the Taylor-Couette flow of shear banding wormlike micelles. We focus on the high shear rate branch of the flow curve and show that for sufficiently high Weissenberg numbers, this branch becomes unstable.

Probabilistic Assessment of the Causes of Active Deformation in Greece, Western Anatolia, and the Balkans Using Finite Element Models

Tectonics, Volume 44, Issue 8, August 2025.
Abstract We constrain the contribution of driving and resistive regional forces to the observed surface deformation in the Nubia‐Eurasia plate boundary region. We use a viscoelastic mechanical model with fault zones representing regional active faults. Deformation is driven by velocities of surrounding plates and by lateral variations in gravitational ...

Impact of Wind‐Wave Coupling on Turbulence and Air‐Sea Fluxes: Insights From Direct Numerical Simulations

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Accurate prediction of air‐sea fluxes hinges on a deep understanding of wind‐wave interactions, yet feedback mechanisms involving surface waves and wind are not fully understood. This paper investigates the effect of two‐way coupling between wind and waves on wind turbulence through direct numerical simulation of air‐water two‐phase flows ...

Transition to magnetorotational turbulence in Taylor–Couette flow with imposed azimuthal magnetic field

New Journal of Physics, 2015
The magnetorotational instability (MRI) is thought to be a powerful source of turbulence and momentum transport in astrophysical accretion discs, but obtaining observational evidence of its operation is challenging.

Numerical Investigation of Liquid Jet Breakup in Rotary Atomizer

Chemical Engineering &Technology, Volume 48, Issue 7, July 2025.
This study presents a numerical analysis of liquid jet breakup in rotary atomization. By comparing different boundary conditions and focusing on gas–liquid interactions, the simulation reveals nonlinear instabilities that govern droplet formation.

Turbulent Taylor–Couette flow with stationary inner cylinder [PDF]

Journal of Fluid Mechanics, 2016
A series of direct numerical simulations were performed of Taylor–Couette (TC) flow, the flow between two coaxial cylinders, with the outer cylinder rotating and the inner one fixed. Three cases were considered, where the Reynolds number of the outer cylinder was $Re_{o}=5.5\times 10^{4}$, $Re_{o}=1.1\times 10^{5}$ and $Re_{o}=2.2\times 10^{5}$.

High quality large‐scale nickel‐rich layered oxides precursor co‐precipitation via domain adaptation‐based machine learning

InfoMat, Volume 7, Issue 7, July 2025.
This work pioneers an AI‐driven defect prediction system and optimized scheduling to enhance the stability of nickel‐rich layered oxide precursors, enabling large‐scale production. With an 83% capacity retention after 500 cycles and exceptional sphericity, it sets a new benchmark for the stable, high‐yield synthesis of advanced lithium‐ion battery ...
