These larger eddies can stir the fluid more efficiently, thereby reducing concentration fluctuations (see figure 4).
The presence of active small-scale turbulence appears responsible for the continuing isotropy of the smallest eddies.
A commonly used procedure to estimate turbulent diffusion times is in terms of enhanced turbulent (eddy) diffusivities.
As soon as t* = 1.5, the velocities become sufficiently high in the wake for a pair of secondary eddies to develop.
In comparing with figure 6, we observe that details of the two spectral eddy-viscosities differ.
However, as the eddy did not increase in size further, this rate decreased downstream of the eddy formation.
For instance, the isotropic eddy viscosity hypothesis does not predict the observed fact that the shear stress and mean velocity gradient vectors have different directions.
In computing the response function, we want to capture the deformation of the fluid eddies while excluding the simple advection due to a large-scale flow.
These eddies or waves would occur and interact randomly in space and time in a natural flow (without excitation).
The inner boundary jet is still evident, but the eddy motion inside it is greater than in the westerly-forcing case.
This changes the size and position of the first eddies that form and thus changes the location and frequency of any coalescence of the eddies.
At higher frequencies, these eddies which formed a t the forcing frequency were small and quickly lost their identities by coalescence.
At higher frequencies, these eddies which form a t the forcing frequency are small and are quickly lost by coalescence.
