为研究潮流能水轮机的局部冲刷发展规律
通过系列水槽实验
对比分析水轮机与单桩冲刷的异同
重点探讨桩柱、机舱和叶轮等结构组件对水轮机冲刷发展的影响机理。研究结果表明:水轮机冲刷过程初期
冲刷深度增长速率和冲刷剖面发展较后续其他阶段更为迅速;冲刷发展前期
水轮机的冲刷深度大于单桩冲刷
后期两者差异逐渐缩小;水轮机与同桩径的单桩相比
平衡状态的最大冲刷深度差异较小
前者的平衡最大冲深约为后者的110.9%
且其下游形成的淤积体体积更大。
This study experimentally investigates the local scour process around a pile-supported tidal stream turbine. The research examines the temporal evolution of scour patterns
comparing turbine-induced scour with traditional monopile scour
while analyzing the distinct contributions of structural components (pile
nacelle
and rotor) to the overall scouring process. Results reveal that the initial scour development around the turbine exhibits accelerated profile evolution and depth progression compared to later stages. The turbine-induced scour depth exceeds that of the monopile during the early phase of the process
though this difference diminishes over time. At equilibrium
the maximum scour depth around the turbine approaches that of an equivalent-diameter monopile
reaching approximately 110% of the monopile scour depth. Notably
the turbine configuration generates a larger downstream sediment mound formation
attributed to the energy extraction process which reduces the flow's momentum and consequently diminishes its sediment transport capacity.
