Aerofoil noise is a central concern for a large range of applications, motivated both by economical and environmental interests. One major contributor to aerofoil noise is the selfnoise, defined as the noise produced by the interaction between the aerofoil blade and the pressure fluctuations in its boundary layer and wake. In the present study, the self-noise of an isolated controlled-diffusion aerofoil is investigated using direct noise computation. A highorder finite difference solver is used to conduct large eddy simulations (and one direct numerical simulation), using a new implementation of an overset grid method. The motivation is to investigate multiple sources of aerofoil self-noise ..View full abstract
