摘要
以提高潮流能水轮机工作效率为目的,采用数值模拟和实验研究相结合的方法,通过改变影响导流罩水动力特性的几个关键参数,对4种不同母线线型的导流罩进行数值模拟,并初步分析开口张角对圆型导流罩水动力学性能的影响。研究结果表明:导流罩对于提高水轮机水动力学性可发挥重要作用,基于Fluent的数值模拟结果与实验值吻合较好,为轴流式潮流能发电装置导流罩的设计提供可行的方法和依据。
Aiming at improving the efficiency of water turbine driven by tidal current, the numerical simulation and experimental study of four different types of diffusers with different flare angles were carried out to investigate hydrodynamic performance of diffusers with variable parameters. The results show that the diffuser plays a great role in improving the hydrodynamic characteristics. And the simulation results obtained by using Fluent software agree well with experimental data. The research can provide a feasible method and reliable basis for the development of axial flow marine current energy converter.
