Discontinuous element pressure gradient stabilizations for compressible Navier-Stokes equations based on local projections

A pressure gradient discontinuous finite element formulation for the compressible Navier-Stokes equations is derived based on local projections.The resulting finite element formulation is stable and uniquely solvable without requiring a B-B stability condition.An error estimate is obtained.
