Predicting the noise generated by complex flows from steady CFD solutions

Use this module to predict the noise generated by turbulent flows from steady CFD solutions. Actran SNGR recovers aerodynamic noise sources from flow simulations performed with CFD codes such as Fluent™, Star-CD™, StarCCM+™, Powerflow™, SC/Tetra™ or OpenFOAM™. The results from an steady flow simulation obtained from a RANS CFD analysis are used from the Actran SNGR to synthesize the noise sources, These sources are then imported into an acoustic computation and are then propagated. Actran SNGR allows addressing the noise generated from turbulent flows in a much faster way than classic aero-acoustic approaches and it is specifically useful when relative levels between different designs are needed such as in optimization loops.

Actran SNGR offers high performance solvers and parallel processing features and is fully integrated in Actran VI.

Actran SNGR can also be combined with Actran VibroAcoustics in order to address aero-vibro-acoustic challenges.

Sample applications:

• Air conditioning modules (HVAC).
• Side mirror noise.
• Airframe noise (landing gear, trailing edge).
• Air distribution systems.
