【摘要】 运用简化风车理论,对海流能水平轴水轮机进行叶片设计。应用计算流体力学软件Fluent对水轮机进行水动力性能数值模拟,分析叶片表面压力分布、流场速度分布和获能特性。在浪流水槽中进行模型试验,将计算结果与试验结果进行对比。研究结果表明:桨距角、尖速比和负载对水轮机的水动力性能有影响,工程上应采取相应措施。更多还原

【Abstract】 The blade of marine current horizontal axis turbine was designed by using Simple Windmill theory. Numericalsimulation of hydrodynamic performance of turbine was made by using computational fluid dynamic software FLUENT,the surface pressure distribution of blade,velocity distribution of flow field and power characteristic were analyzed then.Model experiments were done in wave-current tank,and comparisons were made between calculated and experimentalresults. The studies showed that pitch,tip speed ratio and load have effects on the hydrodynamic performance of turbine,which corresponding measures should be taken in project.更多还原
