Flow Duct

Application ID: 1371

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.

This model example illustrates applications of this type that would nominally be built using the following products:
