摘要：

In this paper, we present our recent work on single relaxation Lattice Boltzmann method and Large Eddy Simulation (LES) models, namely the dynamic Smagorinsky and wall-adapting local eddy-viscosity (WALE). Initially, forced and decaying homogeneous isotropic turbulence cases were run to compare direct numerical simulations with LES. Moreover, the Taylor-Green vortex was employed to further test the performance of the turbulence models under transition to turbulence. The main purpose of this work was the verification for wall-free simulations of the two newly-implemented LES models in the in-house AMROC framework.
