| 摘 要： | 为了考察湍流燃烧过程中的辐射换热效应，用有限体积和概率密度函数输运方程求解相结合的方法模拟了湍流自由射流火焰中的辐射换热，并对湍流辐射交互作用进行研究．计算结果表明，辐射换热作用将使火焰的温度有所降低；湍流辐射交互作用使辐射换热有较大幅度的增强，需要在辐射换热计算中予以考虑．

| Abstract: | In order to gain an understanding of the influence of heat radiation in the tubulent combustion process, the combination of finite-volume method and PDF method is used to simulate the radiation heat transfer in turbulent jet diffusion flames. The PDF method is applied to simulate the interations between turbulence and radiatioru The finite-volume method is responsible for the solution to the averaged radiation transfer equatioru Based on the simulation results, the flames become colder because of radiation heat transfer and TRI do play an important role in the process of radiation. It is suggested that TRI should be taken into account when considering heat radiation problems. |
