本研究的重点是耦合效应所产生的变化，在水动力性能的半潜式浮动风力涡轮机，当它经历风荷载下的大倾角。通过一系列的时域模拟，它表明，无论是船体几何非线性效应和粘性流体动力的变化可以显着影响一个典型的浮动风力涡轮机在额定条件下在波浪中运行的动态。所述的对齐和错位的风和波的影响的后果进行了探讨。一般而言，发现倾斜会增加运动，其中受影响更大的模式取决于入射风和波浪之间的相对方向。了解空气动力耦合的来源是为下一代漂浮式风力涡轮机提供合理设计和建模指导的关键。
This study focusses on the coupling effects arising from the changes in the hydrodynamic behaviour of a semi-submersible floating wind turbine when it undergoes large inclinations under wind loading. By means of a range of time-domain simulations, it is shown that both the hull geometric nonlinearity effect and the alteration of viscous hydrodynamic forces can significantly affect the dynamics of a typical floating wind turbine operating in waves at rated conditions. The consequences of said effects for both aligned and misaligned wind and waves are explored. In general terms inclinations are found to increase motions, where the modes that are more affected depend on the relative direction between incident wind and waves. Understanding the sources of aero-hydrodynamic coupling is key to providing sound design and modelling guidelines for the coming generation of floating wind turbines.
