title = "On the mechanisms of noise reduction in aerofoil-turbulence interaction by using wavy leading edges",
abstract = "A novel aerofoil leading-edge pro_le based on wavy (sinusoidal) protuberances/tubercles is investigated numerically to understand its e_ectiveness for the reduction of aerofoil-turbulence interaction noise. Non-lifting at-plate aerofoils with straight and wavy leading edges (denoted by SLE and WLE, respectively) are employed and subjected to an impinging turbulence that is synthetically generated in the upstream zone. A full three-dimensional Euler (inviscid) simulations are performed for this study in order to avoid developing self-noise due to viscosity. The free-stream Mach number is set to 0.24. A high-order accurate _nite-di_erence based solver and artefact-free boundary conditions are used in the current simulations. Various frequency-spectra and statistical analysis are implemented in order to investigate and understand the noise reduction mechanisms.",
