Abstract

In the research field of aeroacoustics, fluctuations in turbulent flows which are part of a sound generating process can be identified by means of the so-called causality correlation technique [5,6,29]. In this approach, the coefficient matrix resulting from the calculated correlation coefficients between the acoustic pressure fluctuations in the far field and velocity fluctuations in a turbulent flow field is analysed. The temporal resolution of the coefficient matrix is set by the sampling rate of the pressure signal in the far field. The spatial resolution is determined by the spatial sampling rate of the measured flow quantity (Table 11.22).
