Aeroacoustic Simulation: The key to quieter and more efficient products

Control noise with fast and smart solutions using Altair FlightStream

More than just a matter of comfort, the acoustic performance of a product can be crucial for its success in the market. In equipment and systems with high airflow—such as fans, drones, turbomachinery, or automotive systems—the noise generated by the flow itself is a critical factor. In this context, aeroacoustic simulation has become an essential tool to anticipate noise issues early in the design phase, contributing to quieter, more efficient products that meet market expectations.

Computational aeroacoustics allows engineers to predict how sound propagates and identify which regions of a system are responsible for the most noise generation. Turbulence, vortices, flow separation, and interactions with solid surfaces are some of the main sources of noise that can be identified and mapped using this type of simulation. Whether redesigning fan blades, optimizing duct shapes, or defining acoustic barriers, the strategic use of aeroacoustic analysis enables significant improvements without relying on lengthy physical prototyping cycles.

To support this early-stage design process, software like Altair FlightStream stands out for its speed and accuracy. Based on panel methods, FlightStream allows for efficient flow behavior simulation across a wide range of applications, regardless of complexity. With a fully integrated aeroacoustic analysis module, the software can directly compute acoustic fields from flow solutions, significantly accelerating the development cycle. In addition, FlightStream can model both tonal and broadband noise components, enabling a comprehensive characterization of the system’s sound sources.
