This Application Best Practice (ABP) specific example will provide guidance if you want to find noise perdition for a Radiator Fan, an Electronic Fan or any other similar applications. This ABP covers the details such as, the typical mesh, setup, solver numerics, solution procedure and postprocessing relevant to motor fan acoustic.

Learning Outcomes

By the end of this course, you will be able to:

• Understand the fundamentals of aeroacoustic simulations and the differences between CAA (Computational Aeroacoustics) and FW-H Acoustic Analogy approaches.
• Develop a complete workflow for motor fan noise prediction, including CAD preparation, CFD setup, and acoustic model configuration.
• Apply mesh and time-step best practices to accurately capture aerodynamic and acoustic phenomena.
• Configure and run transient SBES-based aeroacoustic simulations in Ansys Fluent using recommended solver settings and procedures.
• Perform FFT-based acoustic post-processing to evaluate SPL, OASPL, blade-passing frequencies, and acoustic source locations.
• Interpret aeroacoustic results, including noise spectra, directivity plots, source identification, and fan acoustic performance
