Abstract:
This paper describes a three-level finite element method for solving the instationary incompressible Navier-Stokes equations. Separating large resolved scales, small resolved scales and unresolved scales enables us to deal with each of these scale groups differently. Whereas the computation of the large scales is performed using a standard Galerkin method, the small scales are resolved by approximate residual-free bubbles exploiting an elementwise submesh with respect to the original discretizat...    »
