| 中文摘要: |
| 大型海上浮式风力机在Froude相似环境下进行模型试验时，模型叶片因尺度效应影响难以满足推力要求．以一款6 MW海上浮式风力机为例，介绍了一种设计模型叶片方法以满足水池模型试验要求．在Matlab中，利用模式搜索法优化工具包，结合美国可再生能源实验室(NREL)的全耦合软件FAST，借助广义动态尾流(GDW)理论重新设计了一款模型叶片，并对所设计的叶片进行了数值计算和CFD计算．计算结果能满足模型试验多种工况的推力要求，表明了该方法的可行性． |
| 英文摘要: |
| It is difficult for a model blade to meet the thrust of a big-scale marine floating wind turbine under the Froude similarity environment in a basin model test, because of scale effect. Taking a 6 MW floating wind turbine as example, a method of designing model blade to satisfy demands of a basin model test is presented. In Matlab, taking the advantage of pattern search optimization toolbar, and combining the full-coupled software FAST of the National Renewable Energy Laboratory (NREL), using the generalized dynamic wake (GDW) theory a model blade is redesigned, and then the blade is tested by numerical calculation and CFD calculation. Lastly, the feasibility of this blade design method under the thrusts of several operating conditions is proved by the calculation results. |
