Taylor microscale,

where, is the mean strain rate

Kolmogorov length scale,

Note:

Kolmogorov length scale ( ) is related to integral length scale ()
( ) - Thickness of the smallest vortex present in turbulent flow

Turbulent Reynolds number based on the length scales

Note:
is the characteristic velocity
