Algebraic Splitting for Incompressible N

Fully discretized incompressible Navier-Stokes equations are solved by splitting the algebraic system with an approximate factorization. This splitting affects the temporal convergence order of velocity and pressure. The splitting error is proportional to the pressure variable, and a simple analysis

A pseudo-spectral approximation for the Navier-Stokes equations in the 2D case is presented using a new splitting technique based on the Uzawa algorithm. The system is decoupled into Helmholtz equations for the velocity and an equation with the pseudo-Laplacian for the pressure. Staggered grids with
