摘要

本文对在由风和波浪组成的复杂海洋环境中漂浮的海上风力涡轮机(FOWT)进行了数值研究。该研究通过使用混合模型qaleFOAM同时考虑了FOWT系统的空气动力学和流体动力学及其相互作用,该模型使用域分解方法将完全非线性势求解器与两相Navier–Stokes求解器相结合。qaleFOAM模型通过将其预测与公共领域的实验和数值结果进行比较来验证,然后将其应用于单向聚焦波中的FOWT建模,该单向聚焦波的峰值周期为42.31s,并伴有11.4m/s的均匀风。结果表明,在这种条件下,FOWT的空气动力学和流体动力学响应之间存在显著的相互作用。此外,它表明FOWT的最极端响应可能不会发生在最高波处。

Numerical Simulation of a Floating Offshore Wind Turbine in Waves Using qaleFOAM
This paper presents a numerical investigation of a floating offshore wind turbine (FOWT) in a complex marine environment consisting of winds and waves. The investigation takes account of the aerodynamics and hydrodynamics of the FOWT system and their interactions simultaneously by using the hybrid model qaleFOAM, which combines a fully nonlinear potential solver with a two-phase Navier–Stokes solver using a domain decomposition approach. The qaleFOAM model is validated by comparing its predictions with experimental and numerical results available in the public domain and then is applied to model the FOWT in a unidirectional focused wave with a peak period of 42.31 s accompanied by a uniform wind of 11.4 m/s. The result reveals a significant interaction between the aerodynamic and hydrodynamic responses of the FOWT in such conditions. Moreover, it demonstrates that the most extreme response of the FOWT may not occur at the highest wave.

期刊介绍: The primary aim of the IJOPE is to serve engineers and researchers worldwide by disseminating technical information of permanent interest in the fields of offshore, ocean, polar energy/resources and materials engineering. The IJOPE is the principal periodical of The International Society of Offshore and Polar Engineers (ISOPE), which is very active in the dissemination of technical information and organization of symposia and conferences in these fields throughout the world. Theoretical, experimental and engineering research papers are welcome. Brief reports of research results or outstanding engineering achievements of likely interest to readers will be published in the Technical Notes format.
