轴流转桨式水轮机 meaning in Chinese

movable propeller turbine

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。
