Abstract: We revisit the detailed experimental and existing numerical results of the EAA benchmark case of a low-pressure axial fan. Thereby, 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 CFD simulation. 2. Evaluating turbulence modeling. 3. Performing a CFD 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, including a possible truncation and interpolation from the CFD to the acoustic grid. 7. The acoustic field computation and validation of its significant physical quantities. We will present physical and methodological details for a successful aeroacoustic fan simulation.
