Exa Corporation, a global innovator of simulation software for product engineering, has unveiled a Flow-Induced Noise Detection (FIND) capability for its existing aeroacoustic computational fluid dynamics simulations software Exa PowerACOUSTICS.
The FIND software can analyse the fluid flow of a design and rank the different noise sources in order of importance. The noise generated can also be listened to before and after design modifications, so that the impact of any proposed improvements can be aurally assessed.
The new software has already been used by BMW Group to perform aeroacoustic evaluations of complete HVAC systems. BMW had previously found that analysis of the flow through standalone components such as ducts or blowers gave incomplete information on the acoustic performance of the whole system.
