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 number $\mathit{Re}_{S}=2\times 10^{4}$ . With an approximate representation of the mean profile by piecewise linear functions, characterised by the boundary-layer thicknesses at the inner and outer cylinder and the angular momentum in the centre, profiles and torques are extracted from the requirement…

Towards boiling Taylor-Couette turbulence
Taylor-Couette (TC) flow is the flow in-between two concentric cylinders which rotate independently. It is together with Rayleigh-Benard (RB) convection, the flow in-between two plates, heated from

High-precision torque measurements reveal no Reynolds-number range with a fixed power law, andFlow quantities such as the axial turbulent diffusivity, the time scales asociated with the fluctuations of the wall shear stress, and the root-mean-square fluctuations ofthe wall sheer stress and its time derivative are all shown to be simply related to the global torque measurements.
