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

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

Heat transfer enhancement and torque reduction by traveling wave-like blowing and suction in turbulent Taylor-Couette flow

Journal of Thermal Science and Technology, 2021
Direct numerical simulations of turbulent Taylor-Couette flows are performed to investigate the effect of a traveling wave control on torque and heat transfer. In the Taylor-Couette flow, inner and outer cylinders are rotating and immobile, respectively,

Bubble dissolution in Taylor–Couette flow [PDF]

Journal of Fluid Mechanics
We 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.
