Large-eddy simulations of chevron jet flows with noise predictions
Aircraft noise reduction is urgently required for sustainable growth in air travel. Noise reduction nozzles are geometrically complex, posing serious challenges for numerical prediction and aero-engine/aircraft design. Among the first few chevron jet noise publications, this work pioneered the numerical prediction of complex nozzle jet noise using hybrid Reynolds-averaged Navier-Stokes and Large Eddy Simulation (RANS-LES). It made significant contributions to EPSRC project (GR/T06629/01). The method is adopted in EPSRC grant EP/I01022X/1 – Aeroengine Aeroacoustic Interactions, and is readily applicable to aerospace industries. Contacts: Professor P.G.
