Abstract

Flow-induced sound can cause human discomfort, and tightening noise regulations highly affects the planning of airports, traffic roads, wind farms, etc. Reliable prognosis of flow-induced sound require high-fidelity simulation tools, not yet existing. This project concerns advanced computational methods, for reliable prognosis of flow induced sound and its propagation to the far field in realistic 3D environments. We will in particular consider wind-tubine noise and volcano infrasound. A high-fidelity simulation of the sound propagation is computational very expensive (both in terms of memory and integration time), due to the vast size of the surrounding medium. This can only be accomplished by employing a very powerful multi-core computer.
