The Aeroacoustics SIG is happy to welcome Prof. Franceso Avallone to present a webinar on Acoustic Liners in Aero Engines. The webinar will be held on the 31st of January, 1430.
Flow-acoustic interaction over an acoustic liner: a physical description.
Short summary: Acoustic liners are a widely adopted noise reduction technology to reduce fan noise in turbofan engines. A detailed description of how an acoustic wave and a turbulent flow interact over an acoustic liner is still missing, which is needed to: (i) improve existing boundary conditions adopted in numerical simulations to model the acoustic liner, and (ii) to develop advance acoustic liners technologies suitable for upcoming ultra-high bypass ration engines. In this talk, results of scale-resolved LBM/VLES high-fidelity numerical simulations are described. Focus is given on the effect of the face-sheet geometry on the acoustic-induced velocity within the face-sheet orifice.
Zoom: The webinar will be held using the Zoom platform. Joining instructions will be emailed to as part of the registration ticket.
The Aeroacoustics SIG is organising an Aeroacoustics conference to be held on the 7th of February in Manchester.
