摘要 烟黑是燃烧过程的重要生成产物,对燃烧系统中辐射换热有着重要的影响。针对一维平行平板介质的辐射传递过程求解算例,本文改进RADCAL程序,采用三个烟黑辐射模型,研究了烟黑颗粒分别与水蒸气、二氧化碳及其混合物三种情况的非灰辐射,考察了三类模型的适用范围,为燃烧换热提供了参考依据。 Soot is one of the important combustion products,which play a key role for radiative transfer in various areas of engineering.Based on the improved RADCAL program,three soot radiative models were employed to investigate the non-gray radiation from combustion products between two planar plates.The spectral emissivity,total emissivity and intensities of soot and gases mixtures（soot/H_2O,soot/CO_2,soot/H_2O/CO_2）were considered in present paper.These comparisons can provide the basis for the research of radiation heat transfer characteristics under combustion mode.
