摘　　要：为得到更加精确的碳氢燃烧火焰的辐射计算结果,采用将基于HITEMP光谱数据库而建立的光谱模型——FSK模型与可准确计算高方向分辨率辐射强度的DRESOR法相耦合的方式,对一维平板系统内的CO2和H2O的混合气体介质的辐射情况在不同工况下展开计算,得到辐射强度及辐射热流分布,并与其他方法进行分析比较,从而检验该方法的精确性及适用性。In order to obtain more precision results of radiation calculation. A way of correct coupling between the following model and method is adopted. The FSK model,a spectral model is established based on HITEMP spectral database. The DRESOR method,which can calculate the radiation intensity with high direction resolution accurately. Carry out the results of the radiation for mixed media of CO2 and H2O in the one dimensional flat system under different cases. After obtain the radiation intensity and radiation heat flux distribution,analyzing and comparing with other method thus will test the accuracy and applicability of the method.
