【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。
[Abstract]:Based on the simplified windmill theory, the blade design of marine current energy horizontal shaft turbine is carried out. The hydrodynamic performance of hydraulic turbine is simulated by computational fluid dynamics software Fluent, and the surface pressure distribution, flow field velocity distribution and energy capacitation characteristics of turbine are analyzed. The model test is carried out in the wave current flume, and the calculated results are compared with the experimental results. The results show that pitch angle, tip velocity ratio and load have influence on the hydrodynamic performance of hydraulic turbine, and corresponding measures should be taken in engineering.
