Local flow properties in relation to noise generation for low-noise high-lift configurations

less contribution to the sound pressure level than the trailing edge ap. This is in agreement with results from a separate computational aero-acoustics analysis. The analysis of combined temporal and spatial correlations, cross correlations, indicate that the largest correlations are seen for zero or very small separation times for many of the considered point pairs. The dominating frequencies of the cross correlation are sorted out through spectral analysis.
