Abstract

The self-noise of an isolated controlled-diffusion aerofoil is investigated using direct noise computations. The motivation is to investigate the multiple sources of aerofoil self-noise on a realistic compressor blade geometry, the physical mechanisms leading to the generation of sound, and the influence of compressibility effects. The use of direct noise computation allows to obtain a detailed and accurate picture of both the hydrodynamic and acoustic fields. The high-order finite difference solver HiPSTAR is used to conduct the numerical simulations. In the context of the present study, the capabilities of HiPSTAR have been extended with an overset grid framework. The framework employs a ..
