In this work, the Dirichlet, Neumann and linear Robin conditions for the convection–diffusion equation (CDE) lattice Boltzmann (LB) method is investigated and a second-order boundary scheme is proposed for the D2Q9 multiple-relaxation-time (MRT) LB model. With the proposed scheme, consistent impleme...
