Transient Dynamics in Counter-Rotating Stratified Taylor–Couette Flow
Mathematics, 2023 This study focuses on the investigation of stratified Taylor–Couette flow (STCF) using non-modal analysis, which has received relatively limited attention compared to other shear flows. The dynamics of perturbations under different temperature conditions

Routes to turbulence in Taylor–Couette flow
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023 Fluid flows between rotating concentric cylinders exhibit two distinct routes to turbulence. In flows dominated by inner-cylinder rotation, a sequence of linear instabilities leads to temporally chaotic dynamics as the rotation speed is increased. The resulting flow patterns occupy the whole system and sequentially lose spatial symmetry and coherence ...

Salt-Induced Modulation of Self-Assembly in C8-10 AlkylPolyGlucoside/Fatty Alcohol Formulations. [PDF]
ChempluschemSalt's effect on the APG:1‐Dodecanol system was studied. Small‐angle X‐ray scattering showed salt increased interparticle correlation, leading to higher structural organization at higher salt concentrations. This correlates with observed viscoelastic properties. Cleaning efficiency tests were also conducted on samples.

"Barber pole turbulence" in large aspect ratio Taylor-Couette flow [PDF]
, 2000 Investigations of counter-rotating Taylor-Couette flow (TCF) in the narrow gap limit are conducted in a very large aspect ratio apparatus. The phase diagram is presented and compared to that obtained by Andereck et al.

Journal of Thermal Science and Technology, 2016 Contributions of the advection, turbulent transport and diffusion terms to the Nusselt number and the torque coefficient in the Taylor-Couette flow were evaluated. Integrating the energy equation in the Taylor-Couette flow twice gave an equation in which

Azimuthal velocity profiles in Rayleigh-stable Taylor-Couette flow and implied axial angular momentum transport [PDF]
, 2014 We present azimuthal velocity profiles measured in a Taylor-Couette apparatus, which has been used as a model of stellar and planetary accretion disks. The apparatus has a cylinder radius ratio of $\eta = 0.716$, an aspect-ratio of $\Gamma = 11.74$, and ...

Taylor-Couette flow of unmagnetized plasma [PDF]
Physics of Plasmas, 2014 Differentially rotating flows of unmagnetized, highly conducting plasmas have been created in the Plasma Couette Experiment. Previously, hot-cathodes have been used to control plasma rotation by a stirring technique [C. Collins et al., Phys. Rev. Lett.

Hydrodynamic education with rheoscopic fluid [PDF]
EPJ Web of Conferences, 2019 We present a educational poster supporting the subject „Mechanics of fluids I“, which the students evaluate to be difficult mainly due to abstractness. Our goal is to show in vivo the behavior, especially the non-linearity, of various flows transiting into

Mechanism of Vortices Appearance in the Taylor-Couette Flow System [PDF]
Journal of Applied Fluid Mechanics, 2022 This work is devoted to study the Taylor-Couette flow at the early structuring stages. It is aimed to gain insight on the Taylor and Ekman vortices genesis mechanism since the first hints of presence detected at Ta=10-4. Simulations are carried out using
