潮流能涡轮机是潮流能转换的核心设备。本文首先在实验室对所设计的潮汐流涡轮机的性能进行了测试，然后利用该叶轮进行了海水淡化实验。该新型装备已在渤海进行了海试。实验结果表明，新研制的涡轮机效率可达47.6%；相应的叶尖速比为3.5～6。在大偏航角的情况下，涡轮仍能保持较高的工作效率。当潮汐流速度超过1.0米/秒时，压力可增至3.5Mpa，在此条件下，可以通过反渗透膜对海水进行淡化。淡化水的电导率约为540μS/cm。水动力性能实验中，水轮机自启动流速为0.745米/秒，启动扭矩为1牛米；海水淡化实验中，水轮机自启动流速为0.97~1.0米/秒，启动扭矩为10~15牛米左右。相信利用潮流能涡轮机淡化海水是一次很好的尝试，为扩大海洋能的利用提供了实践基础。版权所有 © 2015 约翰·威利父子有限公司
Tidal current turbine is the core equipment to convert the tidal current energy. In this paper, the performance of the designed tidal current turbine is tested in the laboratory, then the impeller is used to conduct an experiment on the desalination of sea water. The sea test of the novel equipment has been done in BoHai Sea. The experimental results indicate that the efficiency of the newly developed turbine could reach up to 47.6%; the corresponding tip speed ratio is from 3.5 to 6. Under the condition of big yaw angle, the turbine could still remain high working efficiency. When the tidal current velocity exceeds 1.0 m/s, the pressure may increase to 3.5 Mpa, and under this condition, sea water can be desalinated through reverse osmic membrane. The electrical conductivity of desalinated water is around 540 μS/cm. For the experiment on hydrodynamic performance, the self‐starting flow velocity of the turbine is 0.745 m/s, the staring torque is 1 Nm while about 0.97–1.0 m/s self‐starting flow velocity and around 10–15 Nm starting torque for the experiment on desalination of sea water. It is believed a good attempt by using tidal current turbine in the desalination of sea water, providing the practice basis on expanding the utilization of ocean energy.
