We continue our seminar series this new year, 2025, on Thursday, Jan. 16th at 13.00
On site: Salón de Grados (Leganés)
For this event in the Aerospace PhD Seminar Series, we had the pleasure of hosting Dr. Francesco Avallone, Full Professor in Fluid Dynamics at the Politecnico di
Torino.
The event took place in the Salón de Grados on Thursday, January 16th at 13:00 pm and was streamed (Online).

Francesco Avallone is Full Professor in Fluid Dynamics at the Politecnico di Torino since May 2023. Previously, he was Tenured Assistant Professor at the at Delft University of Technology, where he did also a two-years PostDoc. He received both his MSc and PhD degrees from the University of Naples Federico II. His PhD focused on non-intrusive techniques for boundary layer transition in hypersonic flows. Since 2015 he works in the field of Aeroacoustics. He has been awarded the ERC StG in 2022 to study the flow acoustic interaction over an acoustic liner. He has worked in several international and national project and has been author and co-authors of more than 80 journal publications and 80 conference papers. He has been supervisor of more than 10 PhD candidates, 6 of them already obtained the PhD. His research interests are airfoil self-noise, rotor noise, acoustic liners, HVAC and fan noise. He is interested in both the physical understanding of the noise generation mechanisms and the development of novel noise reduction technologies. For his research he uses both experimental and computational techniques.
“Flow-Acoustic Interaction Over an Acoustic Liner”
Abstract:
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.

The seminar begin at 13:00 pm and will take place in the Salón de Grados, Leganés.
No previous registration is required.
