Introduction to Hydrodynamic Instability

MEC631 at École polytechnique (Master level)

Fundamental and advanced concepts of flow instability analysis are introduced. Linear eigenmode analysis in local and global formulations, non-modal description of a linear system response to forcing, and nonlinear saturation effects are the main topics.

Aeroacoustics

MECxxx at École polytechnique (Master level)

Basics of general acoustic theory are covered first: plane and spherical waves, compact and non-compact sources. The generation of sound by flow unsteadiness is then addressed by means of acoustic analogies.
