This Ph. D. thesis presents a study of the reduced-order POD-Galerkin modelling with the objective to develop robust and efficient algorithms for the flow control. The first and second chapters deal with the definition and the computation of POD modal basis, then with the formal construction of reduced-order dynamical models from the Navier-Stokes equations. The case of incompressible flows is presented in detail. In the third chapter, a study of the modelling of a three-dimensional turbulent flow, for which the small-scale modelling problem arises, is carried out: the interactions between POD modes and the effects of the POD basis reduction are qualitatively and quantitatively analysed, by a viscous parameterisation in particular. In the f...
