Abstract

ABSTRACT The further development of the first-order panel method panMARE for simulating floating offshore wind turbines (FOWTs) in time domain is presented in this work. Based on a surface discretisation of platform, tower and rotor with its wake, the three-dimensional aerodynamic and hydrodynamic flow fields are calculated. A free wake deformation model is integrated to capture blade–wake interaction. Hydrodynamic, aerodynamic and mooring loads are cumulated by a six-degrees-of-freedom solver to compute the motion of the FOWT. The presented method is able to simulate unsteady and aperiodic motions and to predict the wake deformations and their influence on the rotor loads due to the platform motion. In order to verify the method, simulation results of the DeepCWind floater with the NREL 5-MW baseline turbine are compared with those obtained in the OC4 project. The ability to capture highly unsteady situations is studied as well by simulating a gust with varying length.

一种浮式海上风力机时域气动和水动力建模完全集成的面板模拟方法

本文介绍了一阶面板法panMARE在时域模拟海上浮式风力机的进一步发展。在对平台、塔架和旋翼及其尾迹进行表面离散的基础上，计算了三维气动流场和水动力流场。结合自由尾流变形模型来捕捉叶片-尾流相互作用。通过一个六自由度求解器对水动力、空气动力和系泊载荷进行累积，计算出FOWT的运动。该方法能够模拟非定常和非周期运动，预测平台运动引起的尾迹变形及其对转子载荷的影响。为了验证该方法，将采用NREL 5-MW基线涡轮机的DeepCWind浮子的仿真结果与OC4项目的仿真结果进行了比较。通过模拟不同长度的阵风，也研究了捕捉高度不稳定情况的能力。
