Noise dissipation mechanisms of an acoustic liner under grazing flow
Francesco Scarano, Angelo Paduano, Francesco Avallone
High-fidelity lattice-Boltzmann very-large-eddy simulations are performed to describe the noise dissipation mechanisms in a single cavity acoustic liner subjected to grazing turbul…
Realistic sheared flow profile effects on acoustic impedance eduction in small 3D-ducts
Lucas A. Bonomo, Julio A. Cordioli, Edward J. Brambley +2
We investigate the influence of realistic sheared grazing flow on acoustic propagation in three-dimensional rectangular ducts. We show that conclusions reached in the literature ab…
Metamaterials and Fluid Flows
Francesco Avallone, Federico Bosia, Yi Chen +20
Understanding and controlling the dynamic interactions between fluid flows and solid materials and structures-a field known as fluid-structure interaction -is central not only to e…
Edge-effects in the turbulent flow over flexible aquatic vegetation
Giulio Foggi Rota, Elisa Tressoldi, Francesco Avallone +1
Riparian vegetation along riverbanks and seagrass along coastlines interact with water currents, significantly altering their flow. To characterise the turbulent fluid motion along…
On the impact of the turbulent grazing flow development on the acoustic response of an acoustic liner
Angelo Paduano, Francesco Scarano, Julio Cordioli +2
The interaction between acoustic waves and turbulent grazing flow over an acoustic liner is investigated using Lattice-Boltzmann Very-Large-Eddy simulations. A single-degree-of-fre…
