Query: Scale-selective dissipation in energy-conserving finite element schemes
  for two-dimensional turbulence   We analyse the multiscale properties of energy-conserving upwind-stabilised
finite element discretisations of the two-dimensional incompressible Euler
equations. We focus our attention on two particular methods: the Lie derivative
discretisation introduced in Natale and Cotter (2016a) and the Streamline
Upwind/Petrov-Galerkin (SUPG) discretisation of the vorticity advection
equation. Such discretisations provide control on enstrophy by modelling
different types of scale interactions. We quantify the performance of the
schemes in reproducing the non-local energy backscatter that characterises
two-dimensional turbulent flows.
