During the 20th century, the development of high power laser enabled scientist to reach a regime known as High Energy Density (HED), where matter is carried under extreme conditions. This allow the development of a new discipline: the laboratory astr

Hydrodynamic instabilities in a lined flow duct have been reported in several experiments. Such instabilities also appear in the numerical solutions of the linearized Euler equations and preclude the accurate prediction of the acoustic field. The obj

Fluid flows play an important role in many natural phenomena as well as in many industrial applications. In this thesis, we are interested in oscillating flows origins from a Hopf bifurcation.The open shear-driven square cavity has two limit cycles s

Le couplage entre processus physico-chimiques et le transfert de matière ou de chaleur peuvent donner lieu à des structures spatio-temporelles induites par des flux convectifs. Ces flux peuvent résulter de gradients de densité ou de tension super

The present work is related to the prediction of oscillations in solid rocket motors inner flow. It consists in a study of the laminar-turbulent transition of the motor’s inner flow, which is represented by a cylindrical injection-driven flow, and
