Large Eddy Simulations Of The Entropic Lattice Boltzmann Method

The large eddy simulation (LES) has not been adequately developed in the entropic lattice Boltzmann method (ELBM) framework. In particular, analysis of high Reynolds number turbulence simulations using ELBM-LES remains to be done. A standard Smagorinsky subgrid scale model in large eddy simulation based on the entropic lattice Boltzmann method was established. Simulations of high Reynolds number turbulence were carried out. The validity and robustness of ELBM-LES were explored for high Reynolds number turbulence simulations. Conclusion: ELBM-LES presented a good effectiveness and robustness in simulations of strong nonlinear turbulent flows at the high Reynolds number range.
