Abstract: 

We consider the numerical solvers for discretized partial differential equations arising from different incompressible flows. We used the finite element discretization method to discretize the Navier-Stokes equations. IFISS (Incompressible Flow Iterative Solution Software) is used to obtained the different grids. We used preconditioned Krylov subspace methods to solve the resulting linear systems. Numerical experimental results are performed to compare the preconditioned iterative solvers for different types of the incompressible flows. We show the efficiency of the Hermitian and Skew-Hermitian preconditioner for the iterative solver such as GMRES (Generalized Minimum Residual Methods)
