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…
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…
