This thesis deals with the shock-cell noise generated by under-expanded supersonic jets in single- and dualstream configurations. Shock-cell noise is generated by the interaction between the turbulent structures of the shear-layer and the shock-cell

International audience; On commercial aircrafts, the adequate pressure ratio between the cabin and the exterior is regulated with circular outflow valves. At an operating pressure ratio equivalent to 17000ft in altitude, a tonal noise is observed at

Understand the underlying physics in a perturbed or controled environment of a jet flow is one of the key to reduce noise emission in an aircraft turbofan engine. A sensitivity analysis of the pressure instability wave has been performed in a single

Colloque avec actes et comité de lecture. Internationale.; International audience; Le bruit de choc est un bruit particulier qui intervient lorsque qu'un jet n'est pas parfaitement détendu. On observe alors des cellules de choc en aval de la tuyèr

The main noise that is perceived inside the cabin of an airplane originates in the turbofan engines and their associated exhaust jets. Due to flight conditions, a pressure difference appears at the exit of the secondary flow which engenders a series

International audience; Shock-cell noise is a particular noise that appears in imperfectly expanded jets. Under these expansion conditions a series of expansions and compressions appear following a shock-cell type structure. The interaction between t
