This thesis investigates aeroelastic instability phenomena arising in coupled fluid–structure interactions, considering the flow around a rigid airfoil mounted on a torsion spring. The focus is on the laminar separation flutter phenomenon, namely a

The attenuation of two-dimensional, boundary-layer instabilities by a finite-length, visco-elastic patch is investigated by means of global linear stability theory. First, the modal stability properties of the coupled problem are assessed, revealing

There are more aspiring artists than available positions for artists in artistic labor markets. For fiction writers, the publication of a first book often means getting the first big break in their literary career and entering the literary world as a

International audience; The onset of pitch-oscillations of a NACA0012 airfoil mounted on a torsion-spring is investigated by the means of a global stability analysis. Experimental studies from literature have shown this configuration undergoing on a

International audience; Fan Blade Flutter is an aeroelastic instability which may occur during the operation of a jet engine, depending on the working conditions of the fan stage. It finds its origins in some various mechanisms, including the impact

Experimental study of labyrinth seal aeroelastic instabilities Abstract In turbomachinery, labyrinth seals are used to control the leakage between high-pressure and low-pressure regions. Therefore, labyrinth seals are key components to reach high per

New fan architectures are more sensitive to aeroelastic instabilities. Flutter happens when the exchange of energy between the fluid and the structure is destabilizing. This exchange is caused by flow fluctuations generated by blades vibration and co

The flutter instability has been the focus of numerous works since the middle of the twentieth century, due to its critical application in aeronautics. Flutter is classically described as a linear instability using potential flow models, but viscous
