Abstract
Aeroacoustic results obtained from the study of the noise generated by turbulent flow over a trailing edge are presented. The test model used was a 5mm flat plate with a sharp trailing edge. Models with and without side walls were studied and the results show the effects of the side wall boundary layer on far-field noise. The effect of trips and wind socks on the measured noise spectra are also presented. Mean and unsteady flow data in the very near trailing edge wake were measured and provides important information on the turbulent noise sources. Such information is needed for the future development and validation of predictive models.
