环形燃烧室出口温度分布系数的研究

RESEARCH ON TEMPERATURE PROFILE FACTOR AT EXIT IN AN ANNULAR COMBUSTOR

由于用扇形段调试燃烧室省气、经济,因此寻找扇形段与全环的出口温度分布系数之间的定量关系,显然具有实际意义。本文对扇形段和全环的出口温度分布系数进行了直观统计,通过拟合计算求得可用扇形段温度分布系数计算全环温度分布系数的经验公式,可用于环形燃烧室温度场调试的工程估算。

The visualized statistics of the temperature profile factors (PF) at exits in an annular combustor and its sectors have been made. The results indicate that the number of heads in a sector has significant effect on PF. The empirical formulae for calculating all-ring combustor PF have been obtained from fitting of statistical data. The relative errors between the calculations with these formulae and the measurements in tests are less than0.045.
