Continuous Synthesis of 2-Methoxyhydroquinone from Vanillin in a Taylor-Couette Disc Contactor. [PDF]

ChemSusChem
This study investigates continuous synthesis of 2‐methoxyhydroquinone (MHQ) from vanillin in a Taylor‐Couette disc contactor (TCDC). The TCDC, a stirred column reactor utilizing Taylor vortices for intense mixing, achieved efficient phase separation and hydraulic stability.

Investigation of transient multiphase Taylor-Couette flow

Alexandria Engineering Journal, 2022
A multiphase, transient, horizontal, Taylor-Couette flow has been investigated numerically. This flow governs thermal performance of self-contained drum motor (SCDM) drive systems.

Scalable Exfoliation of Bulk MoS2 to Single- and Few-Layers Using Toroidal Taylor Vortices

Nanomaterials, 2018
The production of a large amount of high-quality transition metal dichalcogenides is critical for their use in industrial applications. Here, we demonstrate the scalable exfoliation of bulk molybdenum disulfide (MoS2) powders into single- or few-layer ...

Direct numerical simulation of the Taylor–Couette flow with the asymmetric end-wall boundary conditions

Archives of Mechanics, 2016
In the paper the authors present the results obtained during a direct numerical simulation of the transitional Taylor–Couette flow in closed cavity. The spectral vanishing viscosity method is used to stabilize computations for higher Reynolds numbers ...

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

Contribution of advetion, turbulent transport and diffusion terms to Nusselt number and torque coefficient in Taylor-Couette flow

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

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

Through-flow effects on Nusselt number and torque coefficient in Taylor-Couette-Poiseuille flow investigated by large eddy simulation

Journal of Thermal Science and Technology, 2016
Flow in a concentric annular passage with a rotating inner cylinder, which is called Taylor-Couette flow, is important in industrial applications, such as electric motor which requires not only effective cooling of rotating shaft but also saving power ...
