Excited to share our latest scientific article in Acta Acustica journal: "Numerical Flow Noise Simulation of an Axial Fan with a Lattice-Boltzmann Solver"!

Our study dives deep into the field of axial fan, a key component in automotive and industrial applications. Leveraging SIMULIA PowerFLOW, we validate data against the European Acoustics Association (EAA) benchmark platform.

Key findings include:

• Less than 1% deviation in fan efficiency between simulation and experimental data.
• Predicted wall-pressure fluctuations aligned well with experimental results.
• Direct calculation of the far-field noise spectra with a quite satisfactory prediction of both broadband and tonal noise levels compared to the experiment.
• Excellent agreement in broadband and tonal noise within 0.7 dBA of overall sound pressure level.
• Advanced post-processing analysis, shedding light on complex mechanisms of noise generation in the tip clearance, including, among others, a beamforming analysis.
