Abstract
The energy of superfluid turbulence without the normal fluid is studied numerically under the vortex filament model. Time evolution of the Taylor-Green vortex is calculated under the full nonlocal Biot-Savart law. It is shown that for the energy spectrum is very similar to the Kolmogorov’s law which is the most important statistical property of the conventional turbulence, where is the wave number of the Fourier component of the velocity field and is the average intervortex spacing. The vortex length distribution converges to a scaling property reflecting the self-similarity of the tangle.
