A stabilized non-conforming finite element method for incompressible flow
Artikel i vetenskaplig tidskrift, 2006
In this paper we extend the recently introduced edge stabilization method to the case of non-conforming finite element
approximations of the linearized NavierStokes equation.
To get stability also in the convective dominated regime
we add a term giving L2-control of the jump in the gradient over element boundaries.
An a priori error estimate that is
uniform in the Reynolds number is proved and some
numerical examples are presented.
