Flow Duct

The modeling of aircraft-engine noise is a central problem in the field of computational aeroacoustics. The acoustic field in a model of an axially symmetric aero-engine duct, generated by a noise source at the boundary, is computed and visualized.

Results are presented for situations with as well as without a compressible irrotational background flow and for the cases of hard and lined duct walls.
