浮式海上风力涡轮机的流体力学分析是设计过程中的一个基本且耗时的部分，传统上采用计算流体动力学方法进行分析。在这项工作中，提出了一种替代的计算框架，能够显着加快设计过程，精度损失最小。通过使用一个国家的最先进的势流代码，代理模型的目的是近似的响应幅度运营商的任何任意浮动海上风力涡轮机的柱形浮标类型。从准确度和计算量方面衡量的结果表明，这种方法能够以非常高的准确度逼近势流求解器，而计算成本仅为计算成本的一小部分。
The hydromechanics analysis of floating offshore wind turbines is a fundamental and time consuming part of the design process, traditionally analysed with methods of computational fluid dynamics. In this work, an alternative computational framework is suggested, able to significantly accelerate the design process with minimal accuracy loss. Through the use of a state-of-the-art potential-flow code, a surrogate model is developed with the aim to approximate the Response Amplitude Operators of any arbitrary floating offshore wind turbine of the spar buoy type. The results, measured in terms of accuracy and computational effort, demonstrate that this approach is able to approximate the potential-flow solver with very high accuracy at a fraction of the computational cost.
