Poster „Computational Aeroacoustics“

Direct numerical simulation of fluid flow
including sound propagation is not
feasible

Separate modeling through acoustic
analogies (Curle, Lighthill)

Two families of approaches

Integral methods

Volume discretization
methods

Our approach: FEM for Lighthill‘s
inhomogeneous wave equation

Lighthill‘s
inhomogeneous wave equation

Lighthill
tensor

Forward coupling from CFD simulation to
acoustic field simulation

Applications

Airframe noise

Blade noise (fans etc.)
