  We revisit the online repository, the data source, the details of the
experiments, and selected numerical results of the EAA benchmark case of a
low-pressure axial fan. We present the whole aeroacoustic simulation process
and its validation by experimental results. A successful computation of the
flow and acoustic involves the following procedure, including validation:
  1. Obtaining a verified mesh for the flow simulation.
  2. Evaluating turbulence modeling.
  3. Performing a mesh convergence study.
  4. Validating significant flow results concerning a subsequent acoustic
simulation.
  5. Establishing a computational domain and meshing regarding the acoustic
field.
  6. Acoustic source term calculation includes possible truncation and
interpolation from the flow grid to the acoustic mesh.
  7. The acoustic field computation and validation of its significant physical
quantities. The data acquisition was motivated to cover all validation steps
with experimental data regarding this conceptual workflow. We will present
physical and methodological details for a successful aeroacoustic fan
simulation.
