The problem of flow through a lattice of plates that moves in a plane-parallel subsonic stream of ideal gas with a small velocity inhomogeneity, having a nonpotential character, is solved. It is shown that as this takes place, monochromatic pressure waves are generated, whose frequencies are multiples of the frequency of passage of the plates of the lattice. Analytic expressions for the intensity of these waves and also for the magnitude of the radiated acoustic power and its spectral composition are obtained. |
