了解潮汐水轮机对河口河床局部侵蚀的影响，对于设计和维护具有稳定基础的水轮机以及评估其环境影响至关重要。本文介绍了在定常水流条件下，单贯流式涡轮机引起清水冲刷的水槽试验结果。所研究的涡轮机是一种最初与埃克塞特大学合作设计的动量回收升力（MRL）涡轮机。结果表明，涡轮机可引起显著的河床冲刷，特别是当它不旋转和叶片处于特定方向时。这与轴流式涡轮机的先前发现相反。尽管增加了冲刷深度，但发现涡轮机的底板可以提高涡轮机性能并减少对下游水流的不利影响。调查结果突出了定期监测和立即采取维修行动的潮汐装置的重要性。
Understanding the effect of tidal turbines on local erosion of the estuarine bed is crucial for design and maintenance of turbines with stable foundations and assessment of their environmental impacts. This report describes the results of flume experiments on clear-water scour caused by a single cross-flow turbine in steady flow conditions. The turbine investigated is a Momentum Reversal Lift (MRL) turbine originally designed in collaboration with the University of Exeter. Results show that the turbine can cause significant bed scour, particularly when it was not spinning and in a particular orientation of blades. This is opposite to the previous findings for axial flow turbines. The bottom plate of the turbine, although increasing scour depth, was found to increase the turbine performance and reduce adverse effects on the downstream flow. The findings highlight the importance of regular monitoring and taking immediate repair actions for a tidal installation.
