12. Summary of results

The discretization is strong since it is about 45 knots per wavelength. This is why we obtain highly accurate results: the pressure calculated at the least favorable point differs from the theoretical value by less than 1%, for all three formulations: \((u,p)\), \((u,p,\phi )\) and \((u,\psi )\).

It should also be noted that all the models used give identical results.
