Correlations and Scales

Definition: Eulerian Time Correlation (stationary flows)

The Eulerian time correlation is defined as

The Eulerian time microscale then is given by

The Eulerian time macroscale (integral scale)  is defined as

Using the uniform flow and frozen field approximations, the scales may be related. That is
