Wavevector-Frequency Spectrum of Transition Zone Wall Pressure Fluctuations.
Abstract
The laminar to turbulent transition zone continues to be of interest from the flow noise point of view. A theoretical model was developed to predict the radiated component (wavenumber less than or equal to the sonic wavenumber) of the pressure fluctuations that occur in this zone. It is also recognized that wavenumbers greater than the sonic wavenumber are also important because pressure fluctuations at these higher wavenumbers may couple with structural vibrations. Keywords: flow noise; turbulence, pressure fluctuations; boundary layer; transition; theoretical; experimental; spectrum.
