Further Results on an Array Design to Measure the Wavenumber-Frequency Spectrum Beneath an Axisymmetric Turbulent Boundary Layer.

Abstract

This report describes the requirements on a flush mounted array designed to measure the wavenumber-frequency spectrum of the axisymmetric component of wall pressure beneath an axially towed cylinder. Measurement of the low wavenumber content is emphasized. The effect of the wavenumber spectral dynamic range as well as channel-to-channel amplitude, phase and position tolerances are evaluated.
