基于相似理论的潮流能发电水轮机力特性分析研究
|
摘要
以流体力学相似理论为基础,借鉴其在风力发电机中的应用经验,对潮流能发电水轮机力特性进行分析。根据潮流能发电水轮机和小比尺试验模型的相似关系,得到潮流能发电水轮机与小比尺试验模型之间的力特性关系,探索潮流能发电水轮机尺寸缩放对其力特性的影响规律。设计比例模型试验,通过对不同尺寸叶轮的受力进行测量与对比,验证相似理论在潮流能发电水轮机力特性分析中的正确性,为潮流能发电水轮机的模型试验研究和水轮机设计提供一定的参考。
In this paper,the force-related characteristics of tidal turbines are analyzed based on similarity theory of hydrodynamics and its' applications experience in wind turbines. According to the similarity relationship between tidal turbines and small scale test models,the force characteristics between tidal turbines and small scale test models is obtained. Then this paper explores the influence on force-related characteristics produced by the scaling of tidal turbines.In order to validate the correctness of the similarity theory in tidal turbines,the scale model test is designed. Then the force produced on the tidal turbines' rotors with different diameters are tested and contrasted. The paper provides some references for model test research and tidal turbine design.
