Energy-stable discretization of the one-dimensional two-fluid model
J. F. H. Buist, B. Sanderse, S. Dubinkina +2
In this paper we present a complete framework for the energy-stable simulation of stratified incompressible flow in channels, using the one-dimensional two-fluid model. Building on…

Energy-consistent discretization of viscous dissipation with application to natural convection flow
Benjamin Sanderse, Francesc Xavier Trias
A new energy-consistent discretization of the viscous dissipation function in incompressible flows is proposed. It is implied by choosing a discretization of the diffusive terms an…

Structure-Preserving Hyper-Reduction and Temporal Localization for Reduced Order Models of Incompressible Flows
Robin Ben Klein, Benjamin Sanderse
A novel hyper-reduction method is proposed that conserves kinetic energy and momentum for reduced order models of the incompressible Navier-Stokes equations. The main advantage of…
