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…

A bimetric cosmological model based on Andrei Sakharov's twin universe approach
Petit Jean-Pierre, Margnat Florent, Zejli Hicham
The standard cosmological model, based on Cold Dark Matter and Dark Energy (ÎCDM), faces several challenges. Among these is the need to adjust the scenario to account for he prese…
