| 摘 要： | 平行射流输运特性研究具有较重要的理论意义和工程价值，对水平浓淡煤粉燃烧也有较重要的意义。本文实验研究了双平行平面射流动量、能量和质量输运，结果表明：速度分布表现为双射流相互吸引并最终汇合成单一射流；温度分布反映了冷射流为加热射流所卷吸；浓度分布反映了惯性力的占优作用。三种变量分布反映了动量、能量和质量输运性质的根本性区别。

| Abstract: | Dispersion of two - dimensional two plane jets was investigated with the help of experiments. Results showed that based on velocity profile data, two plane jets would converge into the single jet because of the pressure difference between the inner flow zone and outer flow zone, temperature profiles demonstrated that the jet with smaller momentum would converge into the jet with larger momentum, particle concentration profiles could be drawn to the conclusion that particles＇ inertial force plays an important role in the particle dispersion. Furthermore, the most important point is that mixing of momentum, energy and mass is different in essence, which will be discussed carefully in the following papers. |
