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。 Black smoke is an important product of the combustion process and plays an important role in radiation heat transfer in the combustion system. In this paper, an improved RADCAL program is proposed to solve the radiative transfer process of one-dimensional parallel slab media. Three smoke black radiation models are used to study the non-gray radiation of smoke black particles in water vapor, carbon dioxide and their mixtures respectively The scope of application of the three types of models provides a reference for combustion heat transfer.
