摘要
为研究Spar风机模型在规则波作用下的响应,基于3D打印等高精度技术,建立Spar型风机模型,并采用弹性缆张紧式系泊方式保证波浪荷载的准确测量,分析计算得到规则波作用下风机模型所受的波浪力。同时,基于Fluent软件系统,采用VOF方法对风机在规则波下的响应进行了数值模拟,数值模拟结果与实验吻合,风机模型所受到的波浪力幅值随着波高增大而增大。进一步通过分析风机模型自由面处的流态,观察波浪爬坡现象。本文建立的试验方法不仅为数值模拟提供了可靠的验证数据,同时为进一步的实际工程提供可靠的试验数据和方法。
In order to study the regular wave induced response of a Spar-type wind turbine model,a spar model is established based on the high-precision 3D printer technology,elastic tension mooring system is adopted to improve the measurement accuracy of the wave forces,and then calculate the wave forced acted on the spar model under regular waves Meanwhile,the wave-induced response of the spar-type wind turbine model is simulated using VOF method based on the CFD tool,ANSYS Fluent.The wave forces acted on the model tend to increase with increase of wave height.Furthermore,wave run-up along the tube wall is observed through the analysis of the flow pattern around the model.The experimental method in this study not only provides validation data for the numerical simulation,but also providing reliable experimental data and method for future practical engineering.
