Abstract

The fractal dimension of vortex tangles in superfluid turbulence at nonzero temperature was calculated. It was found that the dimension is larger than one. The clarity and exact definition of the vortex filaments in superfluid turbulence allowed to explore the geometry and the topology of the vorticity in a way which is not possible in classical turbulence.
