A three-dimension double-population thermal lattice BGK model for simulation of natural convection heat transfer in a cubic cavity

In this paper, a double-population thermal lattice Boltzmann was applied to solve three dimensional, incompressible, thermal fluid flow problem. The simplest lattice BGK D3Q6 model was proposed to determine the temperature field while D3Q15 or D3Q19 for the density and velocity fields. The simulatio...
