Superfluid 3He-B in the zero-temperature limit offers a unique means of studying quantum turbulence bythe Andreev reflection of quasiparticle excitations by the vortex flow fields. We validate the experimentalvisualization of turbulence in 3He-B by showing the relation between the vortex-line density and theAndreev reflectance of the vortex tangle in the first simulations of the Andreev reflectance by a realistic 3Dvortex tangle, and comparing the results with the first experimental measurements able to probe quantumturbulence on length scales smaller than the intervortex separation.
