Sound Extrapolation Method for Turbulent Flows
In aeroacoustics, the far-field directivity is often computed using the integral solution of the acoustic analogy equations. The sound prediction can be rendered when the turbulent eddies move acr....

Aircraft airframe noise: Computational aeroaoustics of bogie noise
Airframe noise is one of the main noise sources during the approach phase. Flight tests have shown that for large aircraft the main landing gear (MLG) is a dominant airframe noise source . The design ....
