Analysis of noise sources derived from hydrodynamic-acoustic splitting and synthetic turbulence to classify noise emissions of modified fan blade wing tips

Abstract

Acoustic emissions caused by turbulence in fluid flow engines is of high concern regarding its negative environmental impact. For industry of fluid flow engines, the reduction of noise emissions of technical products renders an increasingly important factor for maket competitiveness. In this context, the phrase design-to-noise refers to an attempt to incorporate acoustic effects into an industrial design process that aims to minimize noise emissions in a numerical optimaziation framework.
