Abstract We use experiments and direct numerical simulations to probe the phase space of low-curvature Taylor–Couette flow in the vicinity of the ultimate regime. The cylinder radius ratio is fixed at $\eta =r_i/r_o=0.91$, where $r_i \, (r_o)$ is the inner (outer) cylinder radius. Non-dimensional shear drivings (Taylor numbers ${\textit {Ta}}$) in the range $10^7\leq {\textit {Ta}}\leq 10^{11}$ are explored for both co- and counter-rotating configurations. In the ${\textit {Ta}}$ range $10^8…

Abstract Heat and mass transport are generally closely correlated to momentum transport in shear flows. This so-called Reynolds analogy between advective heat or mass transport and momentum transport
Exact relations between Rayleigh–Bénard and rotating plane Couette flow in two dimensions
Abstract Rayleigh–Bénard convection (RBC) and Taylor–Couette flow (TCF) are two paradigmatic fluid dynamical systems frequently discussed together because of their many similarities despite their


Marginally stable and turbulent boundary layers in low-curvature Taylor–Couette flow
Marginal stability arguments are used to describe the rotation number dependence of torque in Taylor–Couette (TC) flow for radius ratios $\unicode[STIX]{x1D702}\geqslant 0.9$ and shear Reynolds
Momentum transport in Taylor–Couette flow with vanishing curvature
We numerically study turbulent Taylor–Couette flow (TCF) between two independently rotating cylinders and the transition to rotating plane Couette flow (RPCF) in the limit of infinite radii. By using
Stability and turbulent transport in rotating shear flows: prescription from analysis of cylindrical and plane Couette flows data
This paper provides a prescription for the turbulent viscosity in rotating shear flows for use e.g. in geophysical and astrophysical contexts. This prescription is the result of the detailed analysis
Torque scaling in turbulent Taylor–Couette flow between independently rotating cylinders
Turbulent Taylor–Couette flow with arbitrary rotation frequencies ω1, ω2 of the two coaxial cylinders with radii r1 < r2 is analysed theoretically. The current Jω of the angular velocity ω(x,t) =
Ultimate turbulent Taylor-Couette flow.
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) and the wind Reynolds numbers Re(w) is found to scale as Re-w∝Ta(1/2), exactly as predicted by Grossmann and Lohse.
Torque measurements and numerical determination in differentially rotating wide gap Taylor-Couette flow.
A torque maximum for counter-rotating cylinders that deviates from the prediction suggested by van Gils et al. is found and a good agreement in the torques is shown.
Intermittent boundary layers and torque maxima in Taylor-Couette flow
Turbulent Taylor-Couette flow between counter-rotating cylinders develops intermittently fluctuating boundary layers for sufficient counter-rotation. We demonstrate the phenomenon in direct numerical
Direct numerical simulations of local and global torque in Taylor–Couette flow up to Re = 30 000
Abstract The torque in turbulent Taylor–Couette flows for shear Reynolds numbers $R{e}_{S} $ up to $3\times 1{0}^{4} $ at various mean rotations is studied by means of direct numerical simulations
Effects of the computational domain size on DNS of Taylor-Couette turbulence
In search for the cheapest but still reliable numerical simulation, a systematic study on the effect of the computational domain ("box") size on direct numerical simulations of Taylor-Couette flow
High-Reynolds number Taylor-Couette turbulence.
Taylor-Couette flow, the flow between two coaxial co- or counter-rotating cylinders, is one of the paradigmatic systems in the physics of fluids. The (dimensionless) control parameters are the
