The superfluid component of liquid helium has exactly zero viscosity and its rotational motion is constrained by quantum mechanics to very thin vortex filaments of the same circulation. When liquid helium is made turbulent the vortex filaments form a disordered tangle. This article critically reviews recent experiments and calculations to explain the surprising observation that near absolute zero, in the absence of viscous effects, turbulent kinetic energy decays, and to highlight similarities and differences between superfluid turbulence and ordinary classical turbulence. © 2004 Elsevier SAS.
