Contributions to heat and mass transfer between a plasma jet and droplets in suspension plasma spraying

摘要: Keywords: suspension plasma spraying droplet computational fluid dynamics heat and mass transfer In spraying, nano-sized particles are injected via a liquid or solvent into jet. Due to shear by the jet, is fragmented small droplets flying gas flow. The present work has focused on single evaporating environment, considers, one hand, physical analysis of phenomena and, other characterization solvent's thermal motion characteristics evaporation means direct numerical simulation multiphase Specific parameters such as time have been estimated. addition, validation study proposed comparing analysis. flow was based compressible 1-fluid model, modified for handling phase change. employed methods included volume (VOF) approach interface tracking finite volumes structured grids.
