相变及炭黑杂质对氧化铝粒子流辐射特性的影响
Influences of phase transition and carbon soot impurity on the radiative properties of alumina particles flow
摘要
Abstract
The distribution of spectral radiance along the axis at 90° angle was calculated based on backward Monte-Carlo method and Bruggeman effective medium theory for axisymmetric high temperature alumina particles flow. The effective optical constant was calculated with Bruggeman effective medium theory for the alumina particle with multiphase and carbon soot impurity, and then influences of phase transition and carbon soot impurity on the radiative properties of alumina particles flow were analyzed based on backward Monte-Carlo method. The calculated results indicate that the influence of multiphase state on the ultraviolet radiation of high temperature particles flow can not be neglected. The spectral radiance along the axis in high temperature region decreased obviously when a little carbon soot impurity was mixed into the alumina particle. While the wavelength increased to near infrared, spectral radiance along the axis near the spout increased with increasing carbon soot content.关键词
