本文提出动态变臂长竖轴潮流能水轮机优化设计概念。以双盘面多流管法为基础推导动态变臂长潮流水轮机水动力特性公式。模拟不同变臂长水轮机运行工况,验证该优化设计思路。结果表明动态变臂长设计能够改善竖轴潮流水轮机水动力特性,为潮流水轮机的优化设计提出了一种新方法。

In this paper,the conception of vertical-axis turbine with variable radius is put forward for the purpose of optimized design on vertical axis turbine.A computer software based on an amended double-multiple stream model is developed to calculate the hydrodynamic performance of the variable radius of vertical-axis turbine and verify the proposed conception.The numerical results of the vertical-axis turbine with variable radius in oval orbit show the significant improvement on hydrodynamic performance,which provides a novel conception for the tidal turbine optimization design.
