| 摘 要： | 采用红外热像仪对带双级旋流器的模型燃烧室火焰筒壁面温度进行了测量,试验研究不同进气温度、油气比和主燃孔参数对火焰筒壁面温度分布的影响.试验研究表明:主燃孔参数变化对火焰筒壁面温度分布有较大的影响;火焰筒壁面温度值随着进气温度的增加而明显升高,但壁面温度分布变化不大;油气比的变化对壁面温度值影响不太大,但对温度梯度影响较大.所得的试验结果可为新燃烧室设计提供一定的参考依据.

| Abstract: | The infrared thermal imager was used to measure wall temperature profiles of the flame tube within the model annular combustor with dual-stage axial swirler under different inlet temperatures,fuel/air ratios and primary holes parameters.The measurements under different experimental cases show that,the different primary holes parameters have a considerable influence on wall temperature profiles of the flame tube.The wall temperature increases with a rise of inlet temperature,but changes of the wall temperature distributions of the flame tube are not obvious.The influences of different fuel/air ratios on profiles of wall temperature are weak,but these influences on the temperature gradient are large.Results of experiments are useful for the optimum design and development of the advanced annular combustor. |
