Effect of Installation Geometry on Turbulent Mixing Noise from Jet Engine Exhaust

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 Large Eddy Simulation (LES)-based Computational Aeroacoustics (CAA) solver is used to study the impact of the wing installation geometry on the turbulent mixing noise from jet exhaust nozzles in an installed configuration.
