摘　　要：为优化矿用氮气-细水雾防灭火技术中关键组成部分氮气-细水雾雾化装置的设计,利用球形5孔探针对气体经过整体式导叶起旋器在雾化装置扩张段所形成的速度场进行了试验测定,明确了装置的扩张段会形成明显的旋转射流流场。利用Fluent软件对5孔探针所进行的气体旋转射流场特性实验进行数值模拟,所得出的结果与实际实验结果具有较好的相符性,进一步确定了雾化装置内气体旋转射流场的特性,为以后雾化装置起旋器的设计工作奠定了基础。The paper optimums design the equipments of nitrogen-water mist technology for mine fire prevention and extinguishing.We use the five-hole probe to determine the the characteristics of gas swirling jet field in nitrogen-water mist atomization device which is originated from the overall style guide vane rotary device and we determine that the swirling jet is originated from there.Using the Fluent numerical simulation method,we simulate that jet field and the result is in line with experimental results.That proves the characteristics and laids a solid foundation for the design of new vortex devices.
