摘要
潮流能是海洋可再生能源的重要组成部分,为提高潮流能利用效率,本文基于叶素-动量理论(BEM)方法,给出Glauert涡流设计理论在水平轴潮流能叶轮设计上的应用。采用BEM理论和CFD数值模拟方法对设计的潮流能叶轮进行水动力性能分析,计算其在不同叶尖速比下的功率特性,2种方法的结果表现了较好的一致性。在此基础上,基于BEM理论,进一步分析叶片表面的载荷分布情况,选取叶片沿展长方向的3个不同位置,分析翼段的流体动力特性随速比的变化规律。计算结果表明,潮流能叶轮工作特性满足对功率和效率的要求,说明了设计方法的可靠性。本文的研究成果为今后水平轴潮流能叶轮设计及水动力性能预报提供有价值的参考。
Tidal current energy is an important component of marine renewable energy.In order to improve the efficiency of tidal current energy utilization,the application of Glauert eddy current design theory in the design of horizontal axis tidal current turbine(HATCT)is presented based on the blade element momentum method.Secondly,the BEM theory and CFD numerical simulation method are used to analyze the hydrodynamic performance of the designed HATCT,and the power characteristics of the HATCT under different tip speed ratios are calculated.The results of the two methods are in good agreement.On this basis,based on BEM theory,the load distribution on the blade surface is further analyzed,and three different positions along the blade extension direction are selected to analyze the variation of hydrodynamic characteristics of the wing section with the speed ratio.The calculation results show that the working characteristics of the HATCT meet the requirements of power and efficiency,and the reliability of the design method is illustrated.The research results of this paper provide valuable reference for the design of the HATCT and the prediction of its hydrodynamic performance in the future.
