Quasilinear Theory of Generation of Hydroelastic Waves in a Turbulent Boundary Layer over an Elastic Coating

Wave generation in an incompressible turbulent boundary layer over an elastic coating is investigated. A deviation of the coating surface is represented in the form of a superposition of random-phase harmonics. The response of the flow to wavy surface deflection is determined in the quasilinear approximation. Calculations are carried out on the basis of the local turbulent boundary layer model and a numerical solution of the Prandtl equation. The competition equations for fast waves excited on a low-loss coating are obtained. The results of solving these equations are compared with the known experimental data.
