A lattice Boltzmann method for two-dimensional convection-diffusion equation is presented in the paper.The tunable parameters in Chapman-Enskog expansion of the local-equilibrium distribution function are determined in the form of convective coefficient and diffusive coefficient.Some discussion on the method is made.
