Motivated by solving the Navier-Stokes equations, this work presents the implementation and development of a reduced order model, the PGD (Proper Generalized Decomposition).Firstly, this method is applied to solving equations models with an analytical solution. The stationary diffusion equation 2D and 3D, 2D unsteady diffusion equation and Burgers equations and Stokes are processed. We show that in all these cases, the PGD method allows to find analytical solutions with a good accuracy compared to the standard model. We also demonstrate the superiority of the PGD relative to the standard model in terms of computing time. Indeed, in all these cases, PGD was much more rapid than the standard solver (several dozen times). The Navier-Stokes 2D ...
