Ask the Expert – Modeling Airborne Noise using ANSYS CFD
The problem of airborne noise generation, propagation and mitigation is of importance in many engineering applications across different industries including aerospace, automotive, electronics, power, HVAC. This webinar focuses on simulation approaches to aeroacoustic problems in ANSYS CFD. They include a direct Computational Aeroacoustics (CAA) methodology, far-field noise propagation using the Ffowcs Williams and Hawkings acoustics analogy, and broadband noise models. Special attention is paid to obtaining an accurate transient solution of an unsteady turbulent flow which is essential to high-fidelity acoustic predictions. Recommendations on appropriate solver settings, discretization schemes, initial and boundary conditions, and post-processing of acoustic data is provided.
