Numerical Prediction of Inlet Geometry Influence On the In-Duct Acoustics of Small Centrifugal Compressors

[EN] Small centrifugal compressors are employed to boost automotive internal combustion engines or hydrogen fuel cells, amongst other applications. In many scopes, the overall intensity and quality of noise emission is a major concern, so many researchers develop and assess numerical models to predi...
