Melting, Oxidation, Evaporation of Particle in-Flight in Plasma Spray Processes
Melting, Oxidation, Evaporation of Particle in-Flight in Plasma Spray Processes
摘要
A comprehensive numerical model has been developed to investigate the transient behaviors of particle characteristics, such as temperature, melting, evaporation, and oxidation status during argon-hydrogen DC plasma spraying.This model includes heat, momentum and mass transfer of carrier gas, and particle heating, melting, evaporationand oxidation. Special attentions have been paid to the evaporation-induced mass transfer and oxidation-inducedevaporation as well as variable non-continuum phenomena.
