Three Dimensional Numerical Analysis of Plasma Spraying Using Supersonic Plasma Gun

Article Preview

Abstract:

Numerical method is applied to analyze the spraying process using supersonic spraying gun; special attention is paid to temperature and velocity fields of argon plasma flow, including. In term of plasma properties, ionization and recombination of plasma species are taken into consideration. The impact of internal injection channel on main plasma gas flow, both velocity and temperature, are investigated. With full dimensional model, three dimensional properties of plasma flow and internal injection channel impact are revealed.
