An Alternative HSS Preconditioner for the Unsteady Incompressible Navier-Stokes Equations in Rotation Form
We study the preconditioned iterative method for the unsteady Navier-Stokes equations. The rotation form of the Oseen system is considered. We apply an efficient preconditioner which is derived from the Hermitian/Skew-Hermitian preconditioner to the Krylov subspace-iterative method. Numerical experi...
