| Abstract: | This paper established the thermal Lattice Boltzmann model of fluid flow and heat transfer,which is based on double lattice Boltzmann distribution model1]. The temperature distribution adopted D2Q9 velocity model. Based on this thermal lattice Boltzmann model,this paper simulated the formation and evolution of the natural convection of the square cavity. Comparing the simulation results with the traditional calculation results, it can be found that the thermal lattice Boltzmann model on fluid flow and heat transfer has the unique advantage, and the methods and procedures established in this paper are effective. |
