Abstract
This study is concerned with the existence of coherent bundles of quantized vortices, and their importance in creating a flow with the classical Kolmogorov scaling and energy cascade. We show that at finite (non-zero) temperatures, in the presence of turbulent normal fluid, quantized vortices are organized into coherent bundles. We also performed a number of simulations at zero temperature and demonstrate that for a Kolmogorov scaling, and hence a hydrodynamical energy cascade, vortices must be organized into coherent bundles. Finally we analyze the polarization of the vortex tangle and find good agreement with theoretical predictions.
