“…In addition, Chemartin et al [21,22] introduced some features of lightning arcs observed in flight or in the laboratory, and studied the interaction between an unsteady electric arc and electrodes, concluding that the complex geometry of an electrode can result in fluctuation of the arc column. To investigate the phenomenon of lightning swept stroke caused by aerodynamic flow effects, Tholin et al simulated the process of a direct current (DC) arc moving along the surface of an aluminum plate using a numerical approach based on the MHD method and focused on studying the influence of dwell time [23].…”

In order to solve the load problem for aircraft lightning strikes, lightning channel evolution is simulated under the key physical parameters for aircraft lightning current component C. A numerical model of the discharge channel is established, based on magnetohydrodynamics (MHD) and performed by FLUENT software. With the aid of user-defined functions and a userdefined scalar, the Lorentz force, Joule heating and material parameters of an air thermal plasma are added. A three-dimensional lightning arc channel is simulated and the arc evolution in space is obtained. The results show that the temperature distribution of the lightning channel is symmetrical and that the hottest region occurs at the center of the lightning channel. The distributions of potential and current density are obtained, showing that the difference in electric potential or energy between two points tends to make the arc channel develop downwards. The arc channel comes into expansion on the anode surface due to stagnation of the thermal plasma and there exists impingement on the copper plate when the arc channel comes into contact with the anode plate.
