Abstract

The decay of quantized vortex line length in quantum turbulence at zero temperature is studied numerically by solving the Gross–Pitaevskii equation with a small-scale dissipation. The obtained decay of the vortex line length L is consistent with the L ∝ t ^−3/2 behavior which supports the Kolmogorov energy spectrum of quantum turbulence. The mechanism of the decay is discussed.
