| A number of noise prediction codes rely on aerodynamic calculations as input. Researchers in the NASA Glenn Acoustics Branch have used several codes to get the answers they need:
ADPAC:
What do you use when you need to evaluate a propulsion concept that no one has considered before? You can create a virtual model and run some calculations with ADPAC, one of our flexible validated CFD tools. While it takes a while to cover all the capabilities of the code, characteristics of the problems that can be solved include: 2D/axisymmetric/3D/mixed, steady/unsteady, inviscid/viscous, rotating/non-rotating/mixed components, with bleeds, leakages, and injection. ADPAC was developed specifically for propulsion system aerodynamic analysis and can run in parallel to provide quick turn-around time.
The ADPAC code is still under development and is designated as export controlled under EAR -ECCN 9E003.b.2 ADPAC is not currently available for general release. U. S. citizens who represent Government organizations, U. S. aircraft industry, or domestic entities may request the code. + Visit our Noise Prediction Software Requests and Documentation

Wind-US:
Have you read about recent jet noise predictions from JeNo or MGBK and wondered about the mean flow solutions from the Wind-US code? Researchers in the NASA Glenn Acoustics Branch have worked in close collaboration with the Wind-US code developers to ensure that our aerodynamic and acoustic predictions reflect the latest practices in both turbulence modeling and acoustic source modeling. What quantities ought to be validated? How are we going to measure that? The NASA Glenn Jet Noise Prediction team works to answer these questions together.
Wind-US is distributed by the NPARC Alliance.

TURBO
TURBO can be used to study unsteady flows in turbomachinery. It is being developed at the Computational Simulation and Design Center at the Engineering Research Center at Mississippi State University (MSU) with the support of NASA Glenn Research Center, the US Army Research Office, GE Aircraft Engines, and Honeywell Engines Systems and Service.
