| 摘 要： | 本文实验研究了氮气稀释条件下,丙烷层流扩散火焰的抬升特性。主要研究了混合物组分及射流出口速度对丙烷抬升火焰抬升高度的影响,得到了氮气稀释下丙烷抬升火焰的再附着滞后现象,并采用计算方法得出了理论火焰抬升高度,与实验数据进行了对比分析,二者符合很好。

| Abstract: | The liftoff properties of propane laminar jet diffusion flame were investigated experimentally with emphasis on the influences of nitrogen dilution.The influences of the mixture components and the velocity of nozzle exit on the liftoff height were conducted.The reattachment hysteresis phenomenon was found in the experiments.The theoretical liftoff height was calculated and compared with experimental data.They are agreed with each other very well. |
