A new method is presented for correcting the intermediate pressure fields obtained from implicit line solution techniques for both the steady incompressible Navier-Stokes (NS) and Partially Parabolized Navier-Stokes (PPNS) equations written in primitive variable form. The new method gives considerable improvement in the rate of convergence compared to the use of a Poisson equation for the pressure correction. It is applied here to the two-dimensional laminar case, but is applicable to turbulent and three-dimensional flows as well.
