本文对低温油雾喷嘴的流场进行了研究。利用Pro/ENGINEER对喷嘴喷流区域进行了三维建模。利用CFD(计算流体动力学)分析了喷管出口不同距离处的速度场。模拟的速度场与实验结果进行了验证。用SYT-2000型数字式多功能风速仪对风速进行了测量。通过正交实验考察了主要工艺参数对速度和温度的影响。结果表明，冷空气流量越大，喷嘴出口直径越小，风速越高。冷空气温度对测点温度影响最大。最后提出了喷嘴的最佳结构。
An investigation of the cryogenic oil mist flow field of nozzle was carried out in this study. A domain of the nozzle jet area was modeled with Pro/ENGINEER. CFD (Computational Fluid Dynamics) analysis was used to state the velocity field of different distances from the outlet of nozzle. The simulating velocity field was verified with the experimental results. Experimental results on velocity were measured by SYT-2000 digital multipurpose wind speed gage. The orthogonal experiment was designed to investigate the main effects parameters on velocity and temperature. It indicates that higher flow of cold air and smaller diameter of nozzle’s outlet will generate higher velocity. The temperature of cold air has most influence on the temperature of measuring point. Finally the optimum structure of the spraying nozzle was proposed.
