  1. This paper present an ideal and calculation method of the effective operating curve where cavitations characteristic is not change . based on the lifting - line and lifting - surface method , using effective operating curve to control the cavitation type and " new section " design method to extend the width of cavitation bucket . the width will almost increase 30 % than the common section
    提出了保持剖面空泡特征不变的有效运转曲线的思想和确定方法,在升力线和升力面的基础上,应用有效运转曲线控制空泡类型,采用“新剖面”设计方法扩大空泡斗宽度,其空泡斗宽度比常规剖面增加近30左右。
  2. In order to increase the energy dissipation of stepped spillway at iarge unit discharge , the integhty dissipater of aerated splitter pier and steppe characteristics is studied . because of verticaj diffhaion now by aerated splitter and impachng steppe 3 by drop flow , the air concentration and the energy dissipation efficiency are greatly increased ; the potentiality of cavitations is decrease . in special at large unit discharge , this effect is more obvious
    掺气分流墩的增加,明显地改善了阶梯面上的压强分布,消除或减小了阶梯凹角内和立面上部的负压;由于掺气分流墩使水流纵向扩散以及挑流落下后在阶梯上的撞击,使水流的掺气浓度和消能率都得到较大的提高,降低了阶梯面空蚀的可能性,特别是在大单宽流量时,这种效果更为明显。
  3. The numerical simulation and experimental research made on the characteristics of the clearance cavitations in kaplan turbine are described herein ; in which the analysis mainly is concentrated on the characteristics of leakage - vortex caused by the flow of the clearance between blade tip and blade chamber , that occurs at the front - pressure side of the blade , and the intensity of the secondary - flow - vortex ; furthermore , the relationship in between the leakage - vortex , secondary flow vortex , cavitations and erosion are analyzed as well
    摘要对轴流转桨式水轮机轮缘间隙流动及空化特性进行数值模拟和试验研究,重点分析轮缘间隙流动在正面头部泄漏流动所引起的泄漏涡带、二次流动的漩涡强度和空化特性,以及泄漏涡带旋转、二次流动的漩涡与空蚀和磨损之间的关系。
