Influences of pores distribution on thermal radiation properties of ceramic materials

  • 摘要: 通过引入吸收性介质内粒子散射Mie理论,结合多弥散粒子系独立散射理论,针对孔隙具有修正Gamma分布规律的多孔陶瓷提出一种计算热辐射特性的方法,以氧化锆陶瓷为例分析了孔隙分布对热辐射特性的影响.结果表明孔隙分布规律和平均孔径对热辐射特性有显著影响.孔径趋于单弥散分布,将使衰减系数、散射反照率、非对称因子等参数减小,而孔径趋于指数分布,这些参数显著提高.当波长较小时,衰减系数随平均孔径先增大后减小,当波长较大时,衰减系数随平均孔径增大而减小;散射反照率和非对称因子均随平均孔径增大而增大.
