Abstract

The inertial range of scales in the turbulent velocity and scalar power spectra is well-described by k−5/3laws. Hunt & Vassilicos (1991) have shown that a self-similar power spectrum, such as E(k) α k−2p with non-integral scaling exponent p, implies the existence in the turbulence of near-singularities1 that cannot be mere isolated discontinuities in the velocities or their derivatives.
