Abstract

This work deals with modelling the motion of plasma by defining transport equations for neutral particles, ions and electrons. Describing the electric current inside an electric arc with the motion of electrons, the heating effect results from the ionisation and internal collisions inside this flow. For example, an internal collision of an electron and neutral particle decreases the number of neutral particles and increases the number of ions and electrons. So ionisation is modelled by multiphase flow. Keywords: Euler/Euler approach, molecular flow, particle class transport, chargecarrier interaction, Coulomb repulsion.
