Global kinetic energy conservation with unstructured meshes

Research output: Contribution to journal › Article › peer-review

Abstract

Conserving kinetic energy is essential in Large Eddy Simulation (LES) in order that subgrid scale modelling (SGS) is not hidden by numerical errors. High-order schemes, which are not available for unstructured grids, are sufficient but not a necessary condition for energy conservation. The problem addressed here is directly ensuring energy conservation through a careful discretization of the momentum and mass equations, and it is shown that this can be achieved with a low-order scheme for unstructured grids.
