Abstract

Abstract: In the present work, a simple large eddy simulation (LES)-based lattice Boltzmann model (LBM) is developed for thermal turbulence research. This model is validated by some benchmark tests. The numerical results demonstrate the good performance of the present model for turbulent buoyant flow simulation.

Key words: post-buckling, bifurcation, dynamic softening, flexible multi-body system, dynamic stiffening, stability, large eddy simulation (LES), lattice Boltzmann method (LBM), turbulent buoyant flow
