Abstract

The notion of the scalar wavenumber-frequency spectrum of wall pressures is introduced, and its principal specific features are considered. A scalar wavenumber frequency spectrum representing the overall energy of all the wave component of a field of turbulent pressures with a specified wave vector module contains the brief information required for the solution of many problems of aerohydrodynamic acoustics. It is shown that loop filters enable the estimation of a wavenumber-frequency spectrum in the region of small wavenumbers. Despite the difficulty in practical implementation of scalar wave filtration of fields of turbulent pressure fluctuations, the construction of loop filters currently seems to be a promising trend of studies. The proposed methods and the results obtained in this study show that the broadband scalar wave filtration of a field of wall pressures may be performed on the basis of finite-size approximations of an “ideal” scalar wave filter with unit wave sensitivity within a specified range of wavenumbers and zero sensitivity outside this range.
