Abstract

A hybrid simulation approach for the integrated time domain simulation of floating offshore wind turbine (FOWT) is developed based on the open-source codes OpenFOAM and OpenFAST. A dynamic link library is proposed for the aero-servo-hydro-mooring coupling framework. The validation of the present integrated coupling framework is carried out for the OC4-DeepCWind 5MW FOWT. A series of numerical simulations are further performed to investigate the dynamic performance of the DeepCwind FOWT with different regular wave cases and combined wind-wave cases. The hydrodynamic and aerodynamic performance of the FOWT is further examined for different focused wave cases. The simulation results demonstrate that the dynamic responses of the FOWT obtained from the developed framework are consistent with those obtained from the literature. The coupled framework can significantly improve computational efficiency by accounting for wave-structure interactions compared to the full-scale CFD and CFD-ALM methods. The motion amplitudes of the FOWT will be significantly increased in focused wave cases.

fot系统气动-弹性-伺服-水系泊耦合框架的研制

基于开放源代码OpenFOAM和OpenFAST，提出了一种浮式海上风力机（FOWT）集成时域仿真的混合仿真方法。提出了气动-伺服-水系泊耦合框架的动态链接库。对OC4-DeepCWind 5MW FOWT进行了集成耦合框架的验证。在此基础上，对不同规则风浪和组合风浪情况下DeepCwind风力机的动力性能进行了数值模拟。在不同聚焦波的情况下，进一步研究了fot的水动力和气动性能。仿真结果表明，所建立的框架计算得到的动力响应与文献计算结果一致。与全尺寸CFD和CFD- alm方法相比，耦合框架通过考虑波-结构相互作用可以显著提高计算效率。在聚焦波情况下，fot的运动幅值将显著增加。
