Resum
In this work, we present numerical comparisons of some stabilization methods for the incompressible Navier–Stokes. The first is the characteristic-based split (CBS). It combines the characteristic Galerkin method to deal with convection-dominated flows with a classical splitting technique, which in some cases allows us to use equal velocity–pressure interpolations. The other two approaches are particular cases of the subgrid scale (SGS) method. The first, obtained after an algebraic approxim...
