摘要
为降低潮流能水轮机尾流效应对机组间距的影响,合理布置水轮机位置,通过数值模拟和水槽实验的方法对具有单桩支撑结构的潮流能水轮机尾流流场进行研究,在此基础上分析具有单桩支撑结构和不同安装高程对潮流能水轮机尾流流场的影响。结果显示:数值模拟与水槽试验总体上数值模拟与实验结果的趋势具有一致性;单桩结构对纵向近尾流场造成影响,会产生一个谷值突变;安装高程越高则导致沿转轮中心直线处的流速恢复越快。
In order to reduce the influence of the tidal current flow field on the unit spacing,the position of the turbine and the utilization of the marine space resources,the research is studied based on the numerical simulation and the tank test method. On this basis of the flow field of the turbine with a single pile support structure and different installation heights is analyzed. The results show that the numerical simulation is consistent with the results of the tank test. The structure of single pile has obvious influence on the wake flow field. The recovery law of the wake flow in different installation height is different.
