摘要
竖轴固定偏角直叶片潮流水轮机的自启动能力较差。文章根据模型试验的观测分析,利用Fluent软件模拟计算在不同水流速度下叶片在圆周不同位置时的潮流水轮机自启动性能,并与加装叶柵附体的水轮机进行比较,得出加装叶柵附体可以提高水轮机的自启动性及水轮机的水动力性能。
The self-starting performance of the fixed pitch straight-bladed vertical axis tidal turbine is poor.Based on the simulated experiment,its self-starting performance at different flow speed and setting position of blade has been calculated by software Fluent with the results compared with that of the tidal turbine with guide vanes,which indicates that the guide vanes contribute to improve its self-starting and hydrodynamic performance.
