In order to analyze the growth mechanism of silicon faceted dendrite and reproduce its growth realistically, a 3D model based on cellular automaton-lattice Boltzmann method was proposed. The growth of silicon dendrite was simulated via the cellular automaton. The temperature field of solidifying silicon crystal was calculated by the lattice Boltzmann method. The cellular automaton model and the lattice Boltzmann method were coupled together by the latent heat of solidification released during the growth of silicon crystals and a high anisotropy function was introduced, thus simulating the growth of 3D silicon faceted dendrite. The effects of interfacial energy anisotropy and initial undercooling on the morphology of 3D silicon faceted dendrite were analyzed. The results show that 3D silicon faceted dendrites have a strong anisotropy. The 3D model can simulate the growth of silicon faceted dendrites more realistically and accurately.
