We reformulate, using broken spaces, the nonlinear subgrid scale (NSGS) finite element model in which a nonlinear eddy viscosity term is introduced only to the subgrid scales of a finite element mesh. Here, two new subgrid formulations are built by introducing subgrid stabilized terms either at the element level or on the edges by means of the residual of the approximated resolved scale solution inside each element and the jump of the subgrid solution across interelement edges. The amount of subgrid viscosity is scaled by the resolved scale solution at the element level, yielding a self adaptive method so that no additional stabilization parameter is required. Numerical experiments are conducted in order to demonstrate the behavior of the proposed methodology in comparison with some discontinuous Galerkin methods.Submitted by Jairo Amaro (jairo.amaro@sibi.ufrj.br) on 2019-07-09T17:36:25Z No. of bitstreams: 1 ARRUDA_v199_p3227-3236-min.pdf: 475762 bytes, checksum: 247960e6f6647063ba218940c955d752 (MD5)Made available in DSpace on 2019-07-09T17:36:25Z (GMT).
