Abstract

We show that a tangle of material lines in a purely structured, decaying turbulent flow presents flat scalings for the curvature and torsion spectra corresponding to both the inertial and viscous ranges in the energy spectrum and that it acquires a fractal dimension close to 2 resembling a material sheet.
