摘要：

Natural convection in a square cavity is simulated by multiple relaxation time (MRT) lattice Boltzmann method (LBM) with a separate distribution function to solve for the temperature distribution. The Rayleigh numbers examined range from Ra = 10(3) to Ra = 10(6). The simulations are performed for anisotropic thermal case and compared to isotropic thermal case. (C) 2015 Elsevier Ltd.
