Slat noise measurement and numerical prediction in the VALIANT programme

Abstract: In the context of the on-going EC research program VALIANT, mechanisms of slat noise generation are studied on the basis of a simple but representative 2-element (slat and main body) airfoil, for which a detailed experimental aerodynamic/acoustic database has been collected in the open jet facility at Ecole Centrale de Lyon (ECL) at a Reynolds number, based on the airfoil chord, of about one million. Then several CFD/CAA prediction methods have been compared, improved and validated against this database.The ai… Show more

“…Slat noise has been studied from wind-tunnel measurements [4][5][6][7], numerical simulations [8][9][10][11][12], and flyover tests [13]: in all of which the upper slat trailing-edge appears as a potential region for noise emission. A limited number of unswept and untapered high-lift scaled models has been studied in the literature, e.g., the MD30P30N [14][15][16], the Boeing 777 two-dimensional (2-D) high lift [17], and energy-efficient transport [18,19].…”

“…ϕ 0 • In the two other cases, it is kept at the same location. Thanks to the linearity of the Helmholtz problem, it would be possible to simulate a more extended source, for example by adding the results obtained with several source locations as in Manoha et al [26]. For the sake of brevity, only one source will be considered in the following work.…”
