ON ITS INTERACTION WITH A VISCOELASTIC COATING

It has been shown that the maximum interaction between 
turbulent flow and a viscoelastic coating is observed when the coating 
thickness is equal to one quarter of the wavelength of the longitudinal 
deformation of the coating surface. The amplitudes of the longitudinal 
and lateral deformations are equal, which must be taken into account 
in analyzing the mechanism of operation of a compliant coating
