Abstract

Recent experiments have claimed to measure a Kolmogorov energy spectrum in the turbulent flow of helium II. A Kolmogorov spectrum requires a damping mechanism which has strong effects at small length scales but negligible effects at large length scales. We describe such a damping mechanism for helium II based on the mutual friction interaction between the normal fluid component and the superfluid quantized vortex lines. From this mechanism we have derived a damping length scale for the superfluid motion, analogous to the Kolmogorov length scale in classical turbulence.
