PhD in Computational Fluid Dynamics

The main aim of my work is to study the Reduced Order Models (ROM) for solving transfer equations. To perform accurate computations, we need very ne discretizations of the physical problems which leads to large systems of equations to solve. Using ROM allows to reduce the computational times required for solving these systems. The method I am currently developping is based on the Proper Orthogonal Decomposition which is the most used ROM in the field of Computational Fluid Dynamics, and the Krylov subspaces which are spaces used to build numerical methods for large sparse linear systems. The method has been tested for the convection-diffusion equation and is now applied to the Navier-Stokes equations, especially for the academic test case of a driven cavity.
