For different REAL flows (moderate Reynolds, locally isotropic or anisotropic …)

• For different REAL flows (moderate Reynolds, locally isotropic or anisotropic …)

• Necessity to account for explicitly the non-negligible correlation between large-and small scales

III. DESCRIPTION of the FLOW: fluctuating field; PIV for determining small scale properties

• The other tests

• 2-rd order SF with the Kolmogorov constant

• Normalized dissipation which L? Attention to initial conditions versus universality .. However, a reliable test

• The most reliable test is the 1—point energy budget equation, when the pressure-related terms might be neglected (point II).
