锥形旋转水射流的试验研究

EXPERIMENTAL STUDY OF CONICAL ROTATORY WATER JET

研究出一种圆锥形水射流喷嘴，并对其结构特点及压力分布进行了分析，从理论和试验结果论述了影响喷嘴射流扩散角的结构因素，包括叶轮叶片的出口角和射流截面压力分布，文中引入喷嘴的几何特征数Ω来表征喷嘴的旋转强度，可用于衡量喷嘴的质量。

A con ical rotatory waterjetwas studied experimentally。A kind of conicalrotatory waterjets nozzle was developed,The structural features and pressure distribution ofconi cal rotatory waterjetwas analyzed and the factors affecting thejetstructure wasdi scussed.The geometric feature val ue is used to express.the rotatory strength of the jet,andprovide theoretical basis.for measuring nozzle。
