Automatic insertion of a turbulence model in the finite element discretization of the Navier-Stokes equations
Résumé
We consider the finite element discretization of the Navier--Stokes equations locally coupled with the equation for the turbulent kinetic energy through an eddy viscosity. We prove a posteriori error estimates which allow to automatically determine the zone where the turbulent kinetic energy must be inserted in the Navier--Stokes equations and also to perform mesh adaptivity in order to optimize the discretization of these equations. Numerical results confirm the interest of such an approach.
