Turbulent Mixing Noise from Jet Exhaust Nozzle

Understanding the complex turbulent mixing noise sources for jet exhaust nozzles is critical to delivering the next generation of “green” low-noise jet engines. A scalable, compressible Computational Aeroacoustics solver based on Large Eddy Simulation is used to study free-shear layer noise from jet exhaust nozzles.

 

The U.S. Department of Energy’s Leadership Computing Facilities have awarded a combined 4.7 billion supercomputing core hours to 61 science and engineering projects for 2013 with high potential for accelerating discovery and innovation through its Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program.
