The Generation, Evolution and Decay of Pure Quantum Turbulence: A Full Biot-Savart Simulation
Shoji Fujiyama, Akira Mitani, Makoto Tsubota +6
A zero temperature superfluid is arguably the simplest system in which to study complex fluid dynamics, such as turbulence. We describe computer simulations of such turbulence and…
Self-Organization of Vortex Length Distribution in Quantum Turbulence: An Approach from the Barabasi-Albert Model
Akira Mitani, Makoto Tsubota
The energy spectrum of quantum turbulence obeys Kolmogorov's law. The vortex length distribution (VLD), meaning the size distribution of the vortices, in Kolmogorov quantum turbule…
Transient growth of Kelvin waves on quantized vortices
C. F. Barenghi, M. Tsubota, A. Mitani +1
Quantized vortex lines in helium II can be destabilized by a sufficiently large normal fluid velocity which is parallel to the vortex lines (Donnelly - Glaberson instability). We s…
A Kelvin-wave cascade on a vortex in superfluid He at a very low temperature
W. F. Vinen, Makoto Tsubota, Akira Mitani
A study by computer simulation is reported of the behaviour of a quantized vortex line at a very low temperature when there is continuous excitation of low-frequency Kelvin waves.…
Instability of vortex array and transitions to turbulent states in rotating helium II
Makoto Tsubota, Tsunehiko Araki, Carlo F. Barenghi
We consider superfluid helium inside a container which rotates at constant angular velocity and investigate numerically the stability of the array of quantized vortices in the pres…
