Resumo
Experiments on the effect of two-layer compliant coatings on the surface friction of a flat plate at flow velocities of up to 16 m/s carried out in a water tunnel are described. To document the properties of the coatings, the dynamic viscoelastic properties of used rubbers were measured in the frequency range approximately corresponding to the frequency range of wall pressure oscillations at current flow velocities. The data on characteristics of the viscoelastic properties of coatings and experimental data on interaction of coatings with the flow form a database required to test various theories and semi-empirical models for predicting the effectiveness of such interaction.
