Nichol, H. A. and Skrbek, L. and Hendry, P. C. and McClintock, Peter V. E. (2004) Flow of He II due to an oscillating grid in the low-temperature limit. Physical Review Letters, 92 (24). p. 244501. ISSN 1079-7114Full text not available from this repository.
The macroscopic flow properties of pure He II are probed in the limit of zero temperature using an oscillating grid. As the oscillation amplitude passes a first critical threshold, the resonant frequency starts decreasing but the flow remains nondissipative. Beyond a second critical amplitude, the flow undergoes a transition to turbulence and becomes dissipative. Nonlinearity and hysteresis observed between the thresholds are attributed to a boundary layer of quantized vortices.
