Superconvergence by $$L^2$$-projection for a stabilized finite volume method for the stationary Navier-Stokes equations. (English) Zbl 1236.76017
Summary: A superconvergence result is established for the stationary Navier-Stokes equations by a stabilized finite volume method and $$L^{2}$$-projection on a coarse mesh. Like other results in the family of $$L^{2}$$-projection methods, the superconvergence presented in this paper is based on some regularity assumption for the Navier-Stokes problem and is applicable to the stabilized finite volume method with quasi-uniform partitions.
