Abstract

In this paper, the Lattice Boltzmann method (LBM) associated with the Multi-Relaxation Times (MRT) is performed to investigate the three-dimensional (3D) natural convection of the air in a cubical cavity for various values of the Rayleigh number ranged between 103 <Ra<105. The main 3D-LBM-MRT code was compared and validated with the experimental and numerical work for different cases. The main objective of this work is to analyze the heat transfer between the two cold vertical walls and the hot cavity base by using the D3Q7 model for thermal field, and the evolution of the velocity field employing the D3Q19 model. Furthermore, the effects of the conjugate heat transfer also take into consideration to investigate the heat transfer rate by using different values of the thermal conductivity.
