Effects of carrier gas flow-rate and oxygen admixture ratio on particle parameters in Ar-O2 plasma

Taking into account the strong plasma-particle interactions and particle loading effects, a model of plasma-particle interaction of argon-oxygen plasma has been developed for the numerical predict the particle temperature, velocity, trajectory and plasma temperature isotherm during the in-flight treatment. In this model the conservative equations solves the conservative equations to predict the plasma trajectories under local thermal equilibrium condition. It is found that the carrier gas flow-rate strongly affects the particle temperature and the admixture ratio of oxygen to argon affects the plasma temperature isotherm as well as the particle temperature.
