摘　　要：为提高旋转式射流喷头的清洗效率,使用Fluent对喷头的倾斜角度和旋转速度进行模拟仿真,以对旋转式射流喷头的结构进行参数优化。仿真结果表明:随着喷嘴倾斜角度增大,最大冲击压力逐渐降低,当喷嘴倾斜角度超过20°时,最大冲击压力下降明显。喷头旋转速度对最大冲击压力和射流路径均有影响,当喷头转速大于180 r/min时,冲击压力下降明显,当转速大于240 r/min时射流偏移路径逐渐增大。在保证既有足够的打击力,又能驱动喷头旋转的前提下,喷嘴倾斜角度设定在20°左右,旋转速度设定在180 r/min左右最佳。In order to improve the cleaning efficiency of the rotating jet nozzle,this study adopts Fluent software to simulate the tilt angle and rotation speed of the nozzle in order to realize the parameter optimization of the nozzle structure.The simulation results show that with the increase of the nozzle tilt angle,the maximum impact pressure shows a gradually decreasing trend.When the nozzle tilt angle exceeds 20°,the maximum impact pressure decreases significantly.In addition,the rotational speed of the nozzle has a significant effect on both the maximum impact pressure and the jet path.When the nozzle rotational speed exceeds 180 r/min,the impact pressure decreases significantly;and when the rotational speed exceeds 240 r/min,the jet deflection path increases gradually.Therefore,under the premise of ensuring that the nozzle has sufficient striking force and can effectively drive the rotation,the optimal tilt angle of the nozzle should be set at about 20°,and the rotation speed should be set at about 180 r/min.
