How do I use CFD time histories to perform vibro acoustic analysis

Flow induced noise is a major contributor to both interior noise and environmental noise, from fans and ducts, in transportation. Currently, flow induced noise engineering is performed using methods like physical test wind tunnels and noise laboratories, which are both costly and time consuming.

This webinar will focus on the use of the VA One aero-vibro-acoustic module to extract vibro-acoustic loads from pressure distribution time histories, taken from an OpenFOAM CFD calculation of a vehicle ‘A’ pillar. You will see how VA One calculates contributions for the hydrodynamic and acoustic sources from the pressure time history. It will also be demonstrated how these results can then be deployed as sources for vibro-acoustic modeling of interior noise or acoustic radiation.

The range of applications for this simulation is broad and covers applications such as fan noise, duct and shell noise in addition to vehicle wind noise.

This webinar is aimed at engineers and designers who want to acquire a better understanding of the simulation solutions for wind noise and how these solutions can help them characterize the wind noise generation and propagation mechanism in order to improve their product design early on in the design cycle.
