Codice 25/2010 Titolo High Order Methods for the Approximation of the Incompressible Navier-Stokes Equations in a Moving Domain Data 2010-07-15 Autore/i Pena, G.; Prud'homme, C.; Quarteroni, A. Link Download full text Abstract In this paper we address the numerical approximation of the incompressible Navier-Stokes equations in a moving domain by the spectral element method and high order time integrators. We present the Arbitrary Lagrangian Eulerian (ALE) formulation of the incompressible Navier-Stokes equations and propose a numerical method based on the following kernels: a Lagrange basis associated with Fekete points in the spectral element method context, BDF time integrators, an ALE map of high degree, and a robust algebraic linear solver. In particular, the high degree ALE map is appropriate to deal with a computational domain whose boundary is described with curved elements. Finally, we apply the proposed strategy to a test case.
