对Sellers叠加模型[1] 作了阐述和推导。应用传热传质类比原理 ,进行了单排孔及多排孔阵绝热温比的实验研究。实验结果与该叠加模型的计算结果进行了比较和分析 ,两者在实验范围内吻合较好。表明该模型可用于燃烧室多孔冷却火焰筒的壁温预测。
The Sellers superposition model [1] is described and deduced. Applying the principle of heat and mass transfer, the experimental study on the adiabatic temperature ratio of single-row holes and multi-row holes was carried out. The experimental results are compared with the calculated results of the superposition model, and the two agree well with each other in the experimental range. It is shown that this model can be used to predict the wall temperature of the porous cooling combustor.
