摘要:

提出了求解计算席壁结构火焰筒壁温的七热流模型的另一种方法，使得该模型的求解不依赖于实验结果，从而可减小因实验误差所产生的计算误差，提高计算精度。结果表明，壁温的轴向分布规律与依赖于实验的求解方法的计算结果基本吻合。

Abstract:

Another method calculating wall temperature of flame tube with matwall structure by seven-heat-flow model is proposed, which enables to solve themodel independently of experimental. Therefore,the calculation error resulting fromexperimental error can be decreased and the accuracy of calculation can be raised,and the calculation cost can be reduced.The results show that the axial wall temperature distributon of the flame tube with mat-wall stracture calculated by themethod coincide essentially with those calculated by method depending on experiment.
