Implicit-explicit methods based on strong stability preserving multistep time discretizations

Author(s) : Gjesdal, Thor
Description : In this note we propose and analyze novel implicit-explicit methods based on second order strong stability preserving multistep time discretizations. Several schemes are developed, and a linear stability analysis is performed to study their properties with respect to the implicit and explicit eige...

Spectral element simulations of buoyancy-driven flow

Author(s) : Gjesdal, Thor , Wasberg, Carl Erik , Andreassen, Oyvind
Description : This paper is divided in two parts. In the first part, a brief review of a spectral element method for the numerical solution of the incompressible Navier-Stokes equations is given. The method is then extended to compute buoyant flows described by the Boussinesq approximation. Free convection in c...

Variational multiscale turbulence modelling in a high order spectral element method

Author(s) : Gjesdal, Thor , Wasberg, Carl Erik , Reif, Bjorn Anders Pettersson , Andreassen, Oyvind
Description : One of the more promising recent approaches to turbulence modelling is the Variational Multiscale Large Eddy Simulation (VMS LES) method proposed by Hughes et al. [Comp. Visual. Sci., vol. 3, pp. 47-59, 2000]. This method avoids several conceptual issues of traditional filter-based LES by employin...
