| Abstract: | 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. |
| Keywords: | discontinuous finite element methods pressure gradient projection methods compressible Navier-Stokes equations error estimation |
