摘　　要：为优化吹扫用喷嘴内部结构,改善吹扫效果,运用CFD软件对几种典型结构的喷嘴的内部流动进行了有限元仿真,得到了相应的流动特性参数等结果。对比分析了仿真结果,结合各种结构的加工工艺性,提出了渐进抛物线型截面的喷嘴结构方案。最后通过试验数据,证明了采用该结构的喷嘴具有一定的优越性。To optimize the structure and improve the efficiency of blowing nozzles for rolling, the interior flowage of several nozzles with different structure was simulated by FEM, the flow parameters were got. The nozzle with a gradual-changing parabola section was presented based on the simulation result and machining technics. The experimental results show that this nozzle has better performance.
