喷雾

It is found that there is a critical value (25mm) for the distance from the nozzle to the skin surface when the spray time is 40 ms. If the distance is too far or too near, heat extraction process will have different characteristics. The results could provide an applicable method for guiding the Cryogen Spray Cooling of laser therapy.

发现喷雾时间在40ms时，喷嘴到皮肤的距离具有一临界值（25mm），大于或小于此距离喷雾与皮肤的换热作用具有不同的特性，研究结果对于将制冷剂喷雾冷却实际应用于激光治疗鲜红斑痣手术具有重要的指导意义。

Based on the theory of large eddy simulation and the method of VOF , the initial breakup process of fuel liquid jet, which eject from the nozzle exit at the time scale of micro-second level, is investigated. The mechanism of primary atomization is analyzed, and the initial breakup model of liquid jet is presented. By modeling and numerical simulation of atomization for a diesel nozzle under the given conditions, the initial umbrella-like spray shapes are obtained, which fits better with the experimental results. Meanwhile, the droplets secondary breakup process, such as leeward RT breakup, dumbbell-like breakup and droplets coalescence, etc. are exhibited visually.

基于大涡模拟LES理论和VOF方法，考察了燃油喷雾初始时刻即时间尺度为微秒级的液柱破碎过程，分析了初始破碎的机理，给出了该时间尺度下液柱初始破碎过程的模型；通过对一特定条件下的柴油机喷油器的建模和喷雾过程的大涡数值模拟，获得了液柱初始时刻"伞状头部"的喷雾形态，所得计算结果与相应的试验数据符合较好；数值模拟还直观地展现了液滴背风RT破碎、哑铃型破碎以及液滴的聚集融合等液滴的二次雾化过程。

It also gets some modificatory curves. During test, the atomization characteristics is also tested and analyzed. The spray angle and distribution have been analyzed and obtained by experimentation in this system. The spray angle is figured out through the design principle.

通过试验也对喷油器的喷雾特性进行了测试和分析，本系统通过空心锥角喷雾测试方法计算出电控喷油器的雾化角，同时对于喷雾的均匀性分布进行了相应的测量。

Through the combined reform of the outer spaying of the coal cutter,the spraying of the beare,the spra- ying of the transfer spot and the Water curtain,which induce the dust concentration,the job condition has been im- proved and has reaeched the preceptorial purpose to realize the high efficiency and yielding of the working face.
