摘要
Direct numerical simulations for axisymmetric plasma jet are developed to investigate particle plasma spraying process. In this paper we study the plasma jet and we focus mainly on the plasma-particle exchanges. Finite element analysis employing COMSOL multiphysics software is used in this simulation. Finally, comparisons are made with the numerically observed particle Nusselt's numbers and theoretically predicted Nusselt's numbers based on the Ranz and Marshall correlation. The results agree well with those obtained previously.
