ABSTRACT

Local thermodynamic equilibrium (LTE), frequently used as first approximation in modeling of thermal plasma processes, is sometimes unable to explain experimental results. It is particularly true near a wall and a surface impacted by the plasma jet. In this work, a 2-D custom model using the CFD commercial code Fluent was developed for argon-oxygen inductively coupled plasma (ICP) at atmospheric pressure. The assumption of thermal equilibrium was made but not that of chemical equilibrium. The transport properties were calculated using higher-order approximation of Chapman-Enskog theory. Reaction kinetics rates of dissociation and ionization were also considered. The model was applied to a process torch used for carving experiments on graphite, and the distribution of reactive species brought to the surface was analyzed in terms of reaction rate distribution: the experimental effect of different injection geometries on the distribution of the reaction rate is qualitatively reproduced by the model.
