Abstract
In this talk we present a stabilized Backward Difference Formula of order 2- Lagrange Galerkin method to integrate the incompressible Navier Stokes equa- tions at high Reynolds numbers. The stabilization of the conventional Lagrange- Galekin method is done via a local projection technique for inf-sup stable finite elements. We prove the stabilized Galerkin method maintains the accuracy and stability properties of the standard Galerkin one. In addiction, it is flexible in the sense that can be used with any conventional time marching scheme, and is relatively easy to incorporate in any conventional FEM code. This method is closely related with the so called Variational Multiscale Method which have been specially designed for turbulence scales separation modelling. The good results obtained in the simulation of high-Reynolds flows, suggest us that our method would be suitable for simulating more complex turbulent flows.
