The lattice Boltzmann method (LBM) is applied to simulation of natural convection in anisotropic porous media using Brinkman equation. The Brinkman equation is recovered from a kinetic equation for the density distribution function with a forcing term. The temperature equation is calculated by a kinetic equation for thermal energy distribution function. The velocity profiles of the LBM shows good agreement with those of the analytical solutions for the Poiseuille flow and for the Couette flow filled with anisotropic porous media. For various values of Darcy and Rayleigh numbers, the solutions of the LBM are compared with those of earlier studies in natural convection. This paper leads to the conclusion that the LBM can simulate natural convection in anisotropic porous media for the non-Darcy model.
