Two-Temperature Simulation of Subatmospheric Arc Discharge

A two temperature model was used to simulate the arc discharge process used for synthesizing nanoparticles. A 60 A arc between graphite electrodes placed inside a sub atmospheric chamber was simulated. Helium was used as the background gas and the chamber pressure was 10 Torr. The ion current densities and temperatures in the vicinity of the arc were compared against the measurements.
