Abstract

A unified framework for velocity structure functions, sign-singular cancellation measures, multifractal measures of the energy dissipation and absolute values of the velocity derivative ("vorticity"), and the two-scale velocity structure functions is suggested. The scaling behavior of these measures within the inertial subrange is considered and tested using one-dimensional (1-D) velocity measurements from a high Re jet flow. In these tests we used the phase-randomization procedure that appears to be an effective tool in identifying the effects of turbulence intermittency and spectral energy flux. A number of relationships between turbulence scaling exponents are derived and tested. (C) 2001 American Institute of Physics.
