High-order immersed boundary method for subsonic aeroacoustics and compressible Navier-Stokes equationsHigh-order immersed boundary method for subsonic aeroacoustics and compressible Navier-Stokes equations
Abdoulaye Ouattara, David Marx, Christian Prax +3
In computational fluid dynamics, the immersed boundary method is a classical technique to account for complex geometries when Cartesian grids are used, as is the case in finite dif…
Perpendicular rod-airfoil aeroacoustics: experiments and modelling of interaction noise
Marios I. Spiropoulos, Filipe R. Amaral, Florent Margnat +2
During the phase of landing, an important aircraft-noise source emanates from the interaction of the landing-gear wake with the deployed flap. In the present work we cast this prob…
Perpendicular rod wake/aerofoil interaction: microphone array and TR-PIV insights via SPOD and beamforming analysis
Filipe Ramos do Amaral, Marios Ioannis Spiropoulos, Florent Margnat +3
This paper investigates the acoustic and velocity fields due to a circular rod and an aerofoil placed in the wake of, and perpendicular to, a rod. Simultaneous measurements were co…
Experimentally informed, linear mean-field modelling of circular cylinder aeroacoustics
Robin Prinja, Peter Jordan, Florent Margnat
A noise modelling approach is proposed for bluff body wakes such as flow over a cylinder, where the primary noise source comprises large-scale coherent structures such as the vorte…
