Abstract

Abstract One of the methods of modelling the movement of floating wind turbines is the use of the diffraction method. However, this method does not take into account the influence of viscosity; therefore, in many cases, it needs to be extended with a matrix of appropriate coefficients. The effect of viscosity causes both the added mass coefficient and the damping coefficient to increase. The determined coefficients were entered into the ANSYS AQWA program, and the calculation results of the transfer function determined with the use of linear and quadratic damping were presented. The results were compared with the results of the experiment, indicating greater convergence for the quadratic model.

用流体动力学系数模拟浮式风力发电机浮板的粘性效应

摘要浮式风力涡轮机运动建模的方法之一是使用衍射法。然而，这种方法没有考虑粘度的影响；因此，在许多情况下，它需要用适当系数的矩阵来扩展。粘度的影响导致附加质量系数和阻尼系数都增加。将确定的系数输入到ANSYS AQWA程序中，并给出了使用线性和二次阻尼确定传递函数的计算结果。将结果与实验结果进行了比较，表明二次模型具有更大的收敛性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
