水平轴潮流能水轮机设计与数值模拟
A design and numerical simulation of horizontal tidal turbine
摘要
Abstract
To improve the utilization efficiency of tidal energy, the blade element momentum ( BEM) based Wilson model is applied to the design of the horizontal tidal turbine. The CFD method is adopted to calculate the turbine’ s hydrodynamic properties and power output at different tip speed ratios. Based on this data, the power output along the blade span and the 3D flow field are analyzed, and the 2D hydrofoil models at different radii are established to predict its corresponding flow field properties in a 3D model. The calculation results show that the performance char-acteristics of the turbine meet the requirements of the power output and power coefficient of the turbine, and as a result, the design method is proved to be efficient. And the 2D simulation has its limitations, it failed to predict hy-drodynamic properties correctly in places near the hub and tip. This indicates that the 3D effects have a significant impact on both the flow field and the turbine’ s work performance.关键词
