In science:

The necessity of the renormalization of the viscosity means that the rough surface slows the flow down and changes the attenuation.
Surface Roughness and Effective Stick-Slip Motion
In this Section we address the question whether it is possible to extract information on the properties of the rough surface from the frequency dependence of attenuation of transverse oscillations.
Surface Roughness and Effective Stick-Slip Motion
The physical reason is obvious: large-scale attenuation processes on the scale of decay length δ are not very sensitive to the details of surface inhomogeneities with the size R ≪ δ .
Surface Roughness and Effective Stick-Slip Motion
In experiment, the position of this maximum on the frequency dependence of the attenuation can become a direct measurement of the correlation radius (size) of the surface inhomogeneities R.
Surface Roughness and Effective Stick-Slip Motion
