Description
Turbulent pressure fluctuations and acoustical shock
waves formed at pipe discontinuities are the primary source
of flow noise. fhe pipe response is excited by the
fluctuating forces associated with the turbulent pressure
fluctuations. The forcing functions can be determined from
the frequency-wavenumber spectrum of the pressure
fluctuations. A procedure is developed here to obtain the
frequency-wavenumber spectrum due to fully developed
turbulent flow. The data analysis procedures developed in
this study to analyze the pressure fluctuations provide a
good means to determine the frequency-wavenumber spectrum
and represent this data in a clear form. Frequency-wavenumber
spectra have been obtained for simulated pressure
data. In the experimental system designed to collect
turbulent pressure data, it was determined that a recessed
transducer configuration cannot be used in water pipe flow
turbulent pressure fluctuation studies because of the
enhanced turbulence created by the upstream holes.
Therefore, flush mounted transducers are required.
