The contribution of this Ph.D consists in a formalism and a methodology to perform linear stability analysis of turbulent flows. The flow dynamics is modelled using the RANS equations closed with a turbulence model, and we focus on the instabilities associated with the large scale structures of turbulence. A global formulation is adopted so as to allow complex geometries analysis. A discrete framework is considered, where the equations are first discretized and then linearized. In particular, the linearization is performed using finite differences. This procedure ensures the generic character of the method regarding the system of equations such as the turbulence model for example, and avoids tedious analytical linearization. Furthermore, it...
