Abstract

In this paper we present results for the transport properties of nonequilibrium thermal plasmas containing chlorinated hydrocarbons in a temperature range from 1 000 K up to 30 000 K at atmospheric pressure. The calculations are based on the kinetic theory using the classical Chapman-Enskog approach to solve the heavy particle Boltzmann equation. Modeling of electron transport properties is performed on the basis of the unified theory of Kihara and Aono. For the evaluation of thermodynamic and transport properties a multi temperature model is used to consider thermal nonequilibrium between heavy particles and electrons.
