Abstract
SPARK-LES is a Large-Eddy Simulation (LES) code currently under development at the Italian Aerospace Reseacrh Center (CIRA). It solves the fully compressible Navier-Stokes equations discretized on multi-block, structured grids according to the Finite-Volume (FV) method, using different high-order schemes. In this work a detailed comparison between the schemes is presented in the simulation of a Taylor-Green Vortex in order to assess their accuracy and performances. Temporal behaviour of kinetic energy decay rate and enstrophy is given at different mesh resolutions, showing a good agreeement with DNS results at finer grids. Analysis of power spectra confirms the universal energy cascade behavior.
