Abstract

Initial work has been done to develop a prototype large eddy simulation (LES) capability within the COFFE finite-element CFD solver, which is a component of HPCMP CREATE-AV Kestrel. The mathematical framework for the Favre-averaged Navier-Stokes equations is outlined, and four different methods for handling subgrid scale turbulence are discussed. Results from two test cases, the Taylor-Green vortex and tandem spheres at Re = 3, 900, are presented and discussed. The Taylor-Green vortex is a canonical case in LES that tests a solver’s ability to handle the turbulent kinetic energy cascade from large eddies to small vortices to dissipation, while the tandem spheres case assesses its capacity to model complex, unsteady, multi-scale flow at low Mach and Reynolds numbers.
