This paper identifies the source of this problem in the interplay of the global pressure-update formula with the numerical boundary conditions, and presents an improved projection algorithm which is fully second-order accurate, as demonstrated by a normal mode analysis and numerical experiments. In addition, a numerical method based on an impulse formulation of the incompressible Navier-Stokes equations is discussed, which provides another option for obtaining fully second-order convergence in both velocity and pressure. The connection between the boundary conditions for projection methods and impulse methods is explained in detail.
