3 validated aero-(vibro)-acoustic scenarios to predict noise levels

Inside the car’s cabin, and especially for a hybrid or an electric vehicle, the overall noise level is primarily dominated by HVAC, cooling and wind noise.

During this webinar, we demonstrate how to benefit from lean FE models to facilitate the prediction of flow-induced noise. To solve aero-acoustic and aero-vibro-acoustic source generation and propagation, this simulation solution supports three types of scenarios:

• Exterior flow-induced pressure loads that apply to a flexible structural model, such as wind noise
• Interior aerodynamic pressure field on HVAC duct components
• Aerodynamic pressure loading on the blades of a cooling fan or a blower

This aero-acoustic modelling approach enables lean, surface pressure-based source creation for stationary or rotating surfaces with minimized input data requirement from CFD solution for source generation. Coupling the FEM structural solver with FEM AO acoustic solutions, this also allows accounting for installation effects in sound propagation.

This webinar is designed for all 3D CAE and CFD user communities, from experts to analysts, who endeavour to predict and address flow-induced noise at an early stage of the design cycle.
