摘　　要：根据现有的数学模型与工业参数对叶片张开型清洗器进行结构设计,通过使用CFX软件对该清洗器进行流场的模拟计算,对速度场和压力场进行分析,综合比较、探究了不同结构参数,即叶片的最优组数,叶片组间的最优距离,以及叶片与管壁的最佳距离,对空化效果的影响。结果证实叶片的最优组数为2组,得到了组距与叶片垂直高度的最佳比,并发现叶片与管壁的间距越小,负压越明显。对叶片空穴射流清洗器的结构进行了优化。The blade open type cleaner is structural designed on the basis of the existing mathematical model and industry parameters, and the influence of different structural parameters to the cavitation effect is well studies and contrasted, namely the optimal number of the blade groups, the optimal interval between every two groups of them, and the optimal distance between them and the pipe wall, through the simulated calculation of flow field of the cleaner by CFX software and the analysis of velocity field and pressure field. The results confirm that the optimal number of the blade group is 2, help conclude the best ratio of the group interval and blade vertical height, and show a more obvious negative pressure when the distance between the blades and the tube is smaller. The structure of the blade cavitation jet cleaner is optimized after the reaches.
