A LES based on the FVLBM (Finite Volume Lattice Boltzmann Method) was applied to a simulation of the flow around a low-pressure turbine airfoil. The result was compared with the result from a conventional Navier-Stokes based LES as well as the experimental result. FVLBM- LES obtained the result comparable to the Navier-Stokes based LES, and provided a good agreement with the experimental result. FVLBM-LES succeeded in capturing the occurrence and behavior of vortices in laminar separation, transition, and turbulent reattachment processes.
