  This article presents an aeroacoustic workflow (pipeline) to generate a flow
and acoustic dataset for studying flow-induced sound in the context of a
cylinder in cross flow. The numerical simulations are performed using OpenFOAM
(v9 or v10, or v2306) for the flow and openCFS for acoustics using the
perturbed convective wave equation (PCWE) and the dilatation equation of
Ribner. The workflow involves several steps, including the flow simulation, the
acoustic simulation, and post-processing of the results in Python 3.9. The
simulation steps are presented in all their details to verify your own
segregated aeroacoustic solver. The analysis focuses on the acoustic
characteristics of the flow, including sound pressure levels, frequency
spectra, and directivity patterns. The results show good agreement with
literature benchmarking datasets. The article concludes by discussing
applications of the workflow for different cases that involve flow-induced
sound generation.
