WebJan 9, 2012 · The flow structure of strongly turbulent Taylor-Couette flow with Reynolds numbers up to Re i = 2 × 10 6 of the inner cylinder is experimentally examined with high-speed particle image velocimetry (PIV). The wind Reynolds numbers Re w of the turbulent Taylor-vortex flow is found to scale as Re w ∝ Ta 1 / 2, exactly as predicted by Grossmann … WebTaylor-Couette flow is the flow of a viscous fluid sheared in the gap between two rotating coaxial cylinders. Sometimes called the “hydrogen atom of hydrodynamics,” Taylor …
High-Reynolds number Taylor-Couette turbulence.
In fluid dynamics, the Taylor–Couette flow consists of a viscous fluid confined in the gap between two rotating cylinders. For low angular velocities, measured by the Reynolds number Re, the flow is steady and purely azimuthal. This basic state is known as circular Couette flow, after Maurice Marie Alfred … See more A simple Taylor–Couette flow is a steady flow created between two rotating infinitely long coaxial cylinders. Since the cylinder lengths are infinitely long, the flow is essentially unidirectional in steady state. If the inner cylinder … See more Lord Rayleigh studied the stability of the problem with inviscid assumption i.e., perturbing Euler equations. The criterion states that in the absence of viscosity the necessary and … See more In 1975, J. P. Gollub and H. L. Swinney published a paper on the onset of turbulence in rotating fluid. In a Taylor–Couette flow system, they observed that, as the rotation rate increases, the fluid stratifies into a pile of "fluid donuts". With … See more Taylor vortices (also named after Sir Geoffrey Ingram Taylor) are vortices formed in rotating Taylor–Couette flow when the Taylor number ($${\displaystyle \mathrm {Ta} }$$) of the flow exceeds a critical value $${\displaystyle \mathrm {Ta_{c}} }$$ See more • Chossat, P.; Iooss, G.

Taylor-Couette Flow - Princeton University
WebA Taylor-Couette fluid flow can generate a turbulent flow by changing the rotational speed of the inner cylinder and is widely used to study the stability of a fluid. For a viscous fluid, … WebNov 4, 1999 · The flow in the gap between an inner rotating cylinder concentric with an outer stationary cylinder with an imposed pressure-driven axial flow was studied experimentally … WebApr 20, 2012 · Direct numerical simulations (DNS) and large eddy simulation (LES) were performed to study the effects of gravitational and centrifugal potentials on the stability of incom-pressible Taylor-Couette flow. The flow is confined between two concentric cylinders with an inner rotating cylinder while the outer one is at rest. pantone2199c
