Self-Consistent Numerical Simulation of Carbon Arc for Nanoparticle Synthesis

Self-consistent model of atmospheric pressure carbon arc discharge in helium atmosphere was developed in the framework of the nanoparticle synthesis project 1 and implemented into the 3D CFD-code ANSYS CFX, which was highly customized for this purpose. Arc discharge model consists of fluid model for non-equilibrium plasma coupled with models of heat transfer in electrodes, ablation of anode, carbon deposition at cathode and space charge sheathes.
