Abstract
Taking into account the strong plasma-particle interactions and particle loading effects, a plasma-particle interactive flow model for argon-oxygen plasma has been developed. We can predict the particle temperature, velocity, trajectory and plasma temperature isotherm by solving the model numerically during the in-flight thermal treatment of granulated micro-particles under local thermal equilibrium (LTE) conditions. It is found that the carrier gas flow-rate strongly affects the particle temperature, the admixture ratio of argon to oxygen and the plasma temperature isotherm.
