Abstract
This paper summarizes the efforts and main achievements by the authors on the topic of slat noise. Wind tunnel experiments and numerical simulations with a Lattice-Boltzmann commercial code were performed in the studies and cross-correlation techniques were used to process the measured and simulated data. The effect on the noise signature of the Mach and Reynolds numbers, angle of attack, slat settings and excrescences on the slat cove wall were considered. Reliable data were generated and the results corroborated previous observations, revealed tendencies and contributed to elucidate aspects of dominant slat noise generation mechanisms.
