Abstract- We present a brief review of recent work on the numerical simulation of atmospheric-pressure nonequilibrium plasma. In order to simulate plasma at atmospheric pressure, a theoretical model and numerical scheme are presented for solving Poisson窶冱 equation and a set of continuity equations using plasma properties estimated from an electron energy distribution function. Numerical methods, including determination of the computational domain and adoption of correction methods to minimize numerical divergence, are proposed and discussed, and recent work on simulating corona and dielectric barrier discharge is presented. Finally, we assess the prospects of using numerical simulation to develop new insights into the fundamental mechanisms behind atmospheric-pressure non-equilibrium plasmas for improved practical use.

Keywords- Atmospheric-pressure non-equilibrium plasmas, simulation, corona discharge, dielectric barrier discharge
