摘　　要：本文基于300kg/h小型烟草加料系统试验台选择典型外混式空气雾化加料喷嘴为研究对象,利用高速摄影技术,搭建自由空间检测试验台。针对喷嘴在不同雾化压力、料液流量、料液温度等烟草加料工艺条件的雾化锥角进行了试验研究分析,并基于试验结果利用ANSYS Fluent 15.0软件对空气雾化喷嘴的外流场进行了仿真模拟。研究得到了不同雾化压力、料液料液及温度对于雾化锥角的影响,利用该试验结果进行喷嘴外流场仿真模拟,提高了仿真的可靠性及精度。In this paper, a typical external-mix air-blast atomizer was selected which based on the small tobacco feeding system with a flow of 300 kg/h as the research object. A free space testing platform is built by high-speed photography. The atomizing cone angle of atomizer under different atomizing pressure, feed liquid flow rate and feed liquid temperature was studied. Based on the test results, the ANSYS Fluent 15 software is used to simulate the external flow field of air-blast atomizer. The influence of different atomizing pressure,feed liquid flow rate and temperature on the atomization angle is obtained. The reliability and accuracy of external flow field simulation is improved by using the experimental results.
