Vortex-Density Fluctuations, Energy Spectra, and Vortical Regions in Superfluid Turbulence
Vortex-Density Fluctuations, Energy Spectra, and Vortical Regions in Superfluid Turbulence
Measurements of the energy spectrum and of the vortex-density fluctuation spectrum in superfluid turbulence seem to contradict each other. Using a numerical model, we show that at each instance of time the total vortex line density can be decomposed into two parts: one formed by metastable bundles of coherent vortices, …
