Abstract: The Lattice Boltzmann Method of the 2D convection-diffusion equation is described using the nine-speed model on the square lattice.The coefficients in the equilibrium distribution are determined by the convection coefficient and the diffusion coefficient.The simulating results fit well with the theoretical results.

Key words: nine-speed model on square lattice, 2D convection-diffusion equation, lattice Boltzmann method
