A natural decomposition of viscous dissipation in DG methods for turbulent incompressible flows
arXiv:1811.12769
Abstract
In this note we aim at a characterisation of the discretisation of viscous dissipation which allows to distinguish `physical' (also frequently called `molecular', or `resolved') from `numerical' dissipation in DG-discretised incompressible flow simulations.
