Abstract

A new approach to noise prediction is developed and is illustrated using the case of an engine cooling fan. The noise prediction problem is divided into capturing the noise sources in the flow and propagating the noise to observer locations, the latter being the subject of this paper. The air velocities and static pressures from the LES simulation of a rotating fan are recorded on a stationary permeable FWH surface that surrounds moving parts of geometry; later this surface is used as a radiating source input to the BEM acoustic projection. The developed combination of FWH and BEM approaches is implemented in massively parallel LES framework. The approach is validated with sound measurements from a fan in an anechoic chamber.
