Superconvergence by L2L2-projection for a stabilized finite volume method for the stationary Navier–Stokes equations

A superconvergence result is established for the stationary Navier–Stokes equations by a stabilized finite volume method and L2L2-projection on a coarse mesh. Like other results in the family of L2L2-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.
