3D Simulation of Motion of Electrons in Air

Study of the breakdown strength of gases is very important for many engineering applications. The main parameters considered important for characterizing transport and electrical behavior of gases to high externally applied electric fields are the electron drift velocity (W), the mean energy ( ) and Townsends first ionization coefficient ( ). These three quantities are generally referred to as the electron swarm parameters or electron transport parameters.
In the present study, a Monte Carlo program in Fortran 77 is developed, validated and then applied to simulate the electron behavior in presence of a gas under the influence of external electric field. The numerical simulation program, tracks the movement of a swarm of electrons under the influence of the electric field, and self-consistently includes the effects on internal scattering, anisotropic and isotropic collision and both elastic and inelastic processes. Using this numerical simulation program, the electron swarm parameters are calculated for nitrogen and oxygen gases. Since air comprises primarily of these two gases, an estimate of the electron transport parameters in air is also obtained. The program is also used to compute the positions of electrons during the course of simulation.

This 3D graph is useless without units on the axes and a time scale.

Meters? Real time?
