Abstract

The Couette configuration of a fluid contained between two rotating concentric cylinders has proved useful to test and validate the HVBK equations which govern the motion of superfluid helium II. We critically review the current understanding of the superfluid Couette problem and compare theory and experiment, distinguishing between the results obtained with infinitely long cylinders and those obtained at small aspect ratio. After discussing some issues which are still unsolved, we point to what should be fruitful directions of further investigation which can be pursued in the Couette configuration.
