Reducing Fan Noise with Altair's CFD Acoustics

Rotating machinery is found in many different types of applications, such as engine cooling systems, ventilation systems, and wind turbines. With an increasing pressure worldwide to reduce industrial noise pollution, it is important to identify solutions to reduce mechanical flow induced noise. Fans are most often evaluated in stand-alone conditions where any complex component or subsystem often results in increased noise levels. Building physical prototypes, however, is expensive and produces trial-and-error test approaches. It is often too late at that point to make significant changes to the product design or to build more prototypes that will increase the cost and time before a product’s release. Altair® ultraFluidX® helps designers and engineers detect noises in existing complicated production prototypes and reduce noise in simulations before any physical prototype is built. Learn how engineers were able to use Altair’s acoustic solution to set up, record, and reduce the noise from a portable generator cooling fan.
