摘　　要：以潮流发电水轮机的设计为研究背景,分析和总结了基于动量定理方法的四种流管模型(单盘面-单流管模型、双盘面-单流管模型、单盘面-多流管模型和双盘面-多流管模型)在竖轴变攻角水轮机的水动力性能计算中的应用,特别是能量利用率预报方面的应用。说明基于动量定理的模型在求竖轴变攻角潮流发电水轮机的水动力性能方面,能够预报一些定性特性和总体趋势,为水轮机的设计和计算提供一种初步方法。This paper describes and compares 4 streamtube models (single-disk single-streamtube, double-disk single-streamtube, single-disk multi-streamtube and double-disk multi-streamtube models) based on the momentum theory for the hydrodynamic performance prediction of the vertical-axis variable-pitch turbine that may be employed to tap tidal stream energy resources, especially for the prediction of the overall turbine power coefficient. All of these are for the designing of turbines used in tidal stream power plants.
