The motion of tracer particles in turbulent superfluid He down to the zero-temperature limit
C. O. Goodwin, M. J. Doyle, J. A. Hay +4
An injection system for polymer particles, with diameters ranging from 1 to 6 m, has been developed for visualizing flows in superfluid He at temperatures down to 0.14 K. Us…
Apparatus to visualize flows in superfluid He below 1 K
I. Skachko, J. A. Hay, C. O. Goodwin +4
We describe a versatile apparatus for optical observations of experimental processes at temperatures down to 0.1 K. The cooling is achieved by a wet cryostat with a dilution refrig…
Modelling turbulent flow of superfluid He past a rough solid wall in the limit
Matthew J Doyle, Andrei I Golov, Paul M Walmsley +1
We present a numerical study, using the vortex filament model, of vortex tangles in a flow of pure superfluid He in the limit through a channel of width mm for…
No Effect of Steady Rotation on Solid He in a Torsional Oscillator
M. J. Fear, P. M. Walmsley, D. E. Zmeev +2
We have measured the response of a torsional oscillator containing polycrystalline hcp solid He to applied steady rotation in an attempt to verify the observations of several…
Reconnections of quantized vortex rings in superfluid He at very low temperatures
P. M. Walmsley, P. A. Tompsett, D. E. Zmeev +1
Collisions in a beam of unidirectional quantized vortex rings of nearly identical radii in superfluid He in the limit of zero temperature (0.05 K) were studied using time-o…
Dynamics of quantum turbulence of different spectra
P. M. Walmsley, D. E. Zmeev, F. Pakpour +1
Turbulence in a superfluid in the zero temperature limit consists of a dynamic tangle of quantized vortex filaments. Different types of turbulence are possible depending on the lev…
