English abstract:
Using existing aeroacoustic wave equations, we propose a general hybrid aeroacoustic
method, based on compressible flow data. By applying the Helmholtz-Hodge decomposition
on arbitrary domains, we extract the incompressible projection (non-radiating base flow)
of the compressible flow velocity by solving the vector valued curl-curl equation with the
vorticity as forcing term. The resulting vortical flow part is used for computing the acoustic
source term. Computations of the aeroacoustic benchmark case, cavity with a lip, which
involve acoustic feedback, show promising results.
