Abstract: A lattice Boltzmann scheme for the distribution of the displacements in the Beltrami flow is proposed. The concept of Beltrami vertex flow is used to find the structures of the fluid velocities. As a numerical example, we simulated the Arnold-Beltrami-Chidress solution of the Beltrami flow by using the lattice Boltzmann method.

Key words: lattice Boltzmann scheme, Beltrami flow, ABC flow
