Azimuthal velocity profiles in Rayleigh-stable Taylor–Couette flow and implied axial angular momentum transport
We present azimuthal velocity profiles measured in a Taylor–Couette apparatus, which has
been used as a model of stellar and planetary accretion disks. The apparatus has a cylinder
radius ratio of. Flow super-rotation, an angular velocity greater than those of both cylinders,
is observed in the sub-rotating regime. The velocity profiles give lower bounds for the
torques required to rotate the inner cylinder that are larger than the torques for the case of
laminar Taylor–Couette flow. The quasi-Keplerian profiles are composed of a well-mixed …

Azimuthal velocity profiles were measured in a Taylor-Couette apparatus, which has been
used as a model of stellar and planetary accretion disks. The apparatus has a cylinder
radius ratio of η= 0.7158, an aspect-ratio of Γ= 11.74, and axial boundaries attached to the
outer cylinder—known to have significant Ekman pumping. We investigated angular
momentum transport and Ekman pumping in the Rayleigh-stable regime. The regime is
linearly stable and is characterized by radially increasing specific angular momentum. We …
