A lattice Boltzmann model for heat transfer in heterogeneous media

Abstract

So far the lattice Boltzmann (LB) method has matured as a powerful tool to address a diversity of heat and mass transfer challenges. For most practical applications, the variation of thermophysical properties of working media will influence the perfor-

“…As no connectivity is needed in the grid used for the resolution, the LBM is usually classified in the family of so-called meshless methods (Belytschko et al, 1996;Frank and Perré, 2010) with a local formulation. In the domain of heat or mass transfer, the scientific community remains very active in methodological developments able to open new configurations to LBM (Hamila et al, 2016;Chen et al, 2016;Demuth et al, 2016) Considering those characteristics, the LBM provides several advantages: simple numerical development, suitability for parallel computing and easy processing of complex morphologies. We would just emphasize here that the choose of LBM was guided by these advantages in using simply the 3-D morphologies of the materials.…”

A lattice Boltzmann model for heat transfer in porous media

“…[9], a D2Q5 lattice for two-dimensional problems is used for numerical validation. For three-dimensional investigated domains, one can invoke a D3Q7 lattice [21]. Such choice can save computational cost efficiently, which is crucial for industrial-level simulation, as explained in our previous work [20].…”
