Evolution of a Pulse of Charged Vortex Rings in Superfluid Helium

George Gamota, Akira Hasegawa, C. M. Varma

Published Apr 19, 1971• 42 citations
Publisher

Abstract

Experiments with a pulsed beam of charged, quantized vortex rings show that it evolves into a steady-state distribution. This behavior is shown to follow from the Coulomb interaction among the vortices and a negative effective pressure arising from the vortex dispersion law.

Creation of Quantized Vortex Rings in Superfluid Helium

George Gamota

We have produced and observed quantized vortex rings emitted from orifices when superfluid helium is forced through channels at critical velocity. The vortices are identified by measuring their velocity and size, and are found to be in the $n=1$ quantum state.

Vortex-Ring Interactions in Superfluid Liquid Helium

George Gamota, T. M. Sanders

We have observed interactions between collimated monoenergetic beams of charged vortex rings. The cross section for ring-ring interaction is approximately geometrical, consistent with a hydrodynamic interpretation. Capture of free ions by oppositely charged rings has also been observed.

Motion of charged vortex rings in helium II

David C. Samuels, Russell James Donnelly

We show that an ion carried through an electric field by a quantized vortex ring in helium II will cause a symmetric change in the radius of the ring, even though the ion is located asymmetrically on the core of the vortex ring. The localized force on the ion will combine with a specific series of vortex waves to give a uniform growth of the ring with a small component of drift velocity perpendicular to the applied electric field. This type of energy transfer may also play an important role in superfluid turbulence. Our calculations should be valid for localized forces on thin-core classical vortices as well.

Vortex-Ring Creation by Negative Ions in Dilute Mixtures of He3 - He4

George W. Rayfield

We describe an experiment which indicates that the addition of ${\mathrm{He}}^{3}$ impurities to superfluid helium has a pronounced effect on the velocity at which negative ions produce vorticity (vortex rings). The ${\mathrm{He}}^{3}$ impurities have no effect, however, on the creation of vorticity by positive ions.

Motion of vortex ring with tracer particles in superfluid helium

Carlo F. Barenghi, Yu. A. Sergeev

Recent experiments on quantum turbulence in superfluid helium made use of small tracer particles to track the motion of quantized vortices, determine velocity statistics and visualize vortex reconnections. A problem with this visualization technique is that it may change the turbulent flow which it visualizes. To address this problem, we derive and solve the equations of motion of a quantized vortex ring which contains a given number of particles trapped on the vortex core, hence derive a quantitative criterion to determine in which measure small particles trapped in quantized vortices affect vortex motion. Finally we apply the criterion to a recent experiment.
