摘要：

This study implements lattice Boltzmann method-based large eddy simulation (LBM-LES) in a high Rayleigh number turbulent flow of a wall-heated room to validate the prediction accuracy. The impacts of grid resolutions, fluid wall boundary conditions, discrete time intervals, and temperature discrete velocity schemes are discussed.
