Key Takeaways:

NASA researchers are utilizing the Pleiades supercomputer to model turbofan engine aerodynamics and acoustic fields.
The project aims to develop faster and cheaper simulation software for engine configurations, reducing the cost of complex simulations using techniques like sliding mesh.
This research is critical for developing and certifying quieter, more fuel-efficient, and lower-emission turbofan engines.

In the ongoing quest to make airplane engines quieter, a team of NASA researchers is turning to Pleiades, one of the world’s most powerful supercomputers.

Engineers and researchers at NASA’s Ames Research Center at Moffett Field (KNUQ) in California are modeling aerodynamic and acoustic fields around turbofan engines in order to develop software that can model engine configurations faster and cheaper. Project results will be compared to data collected at the Low Speed Anechoic Wind Tunnel at NASA’s Glenn Research Center in Cleveland to determine how the simulation techniques work with the software framework.
