Quantification of acoustic and hydrodynamic fields in flow duct systems

Internal wall pressure fluctuations downstream of a flow disturbance in a cylindrical duct consist of a propagating acoustic field of both plane wave and higher-order acoustic modes superimposed onto hydrodynamic turbulence. Various methods exist in both the time and the frequency domain to separate...
