Abstract Low-temperature plasmas are widely used in propulsion systems, advanced manufacturing, biomedical engineering, and many other applications. Such a problem is extremely difficult to simulate due to its physical complexities in three aspects: multi-physics, multi-scale, and highly non-equilibrium. In order to address these three challenges at the same time, a lattice Boltzmann model is developed for three-species low-temperature plasma in this paper, which is completely different from the conventional models based on magnetohydrodynamic equations. Three different numerical cases are simulated and studied in this paper. The results show that the developed model is highly accurate in the simulation of the fundamental diffusion mechanism. In addition, it can reproduce the correct effects of electrostatics and external electromagnetic field, which are two important factors in low-temperature plasma dynamics.
