本文对浮摆式波浪能转换器（FPWEC）的性能进行了二维数值研究。该机构由摆盘、反作用盘、浮子和阻尼盘几部分组成。在非线性波浪条件下，使用时域分析的FPWEC的性能进行评估。本文采用二次边界元法（BEM）的涡旋模型计算单摆的运动振幅。将浮体与单摆耦合作为多体系统进行研究。在该方法中，采用了涡量层模型和涡量脱落模型两种方法。这些模型与用于在物体表面产生涡并将涡量分散到流体区域的涡方法有关。钟摆的运动是由汉密尔顿原理确定的。计算结果与实验结果进行了比较。
In this paper, a 2-D numerical study has been carried out of the performance of a Floating Pendulum Wave Energy Converter (FPWEC). This body consists of several parts Pendulum plate, reaction plate, Float, and damping plate. The performance of the FPWEC is evaluated under nonlinear wave conditions using time-domain analysis. In this study, the quadric boundary element method (BEM) based vortex model is used to calculate the motion amplitude of the pendulum. The coupled of a floating body and pendulum are investigated as a multibody system. In this method, two different methods are used such as the vorticity layer model and the vorticity shedding model. These models are related to the vortex method used to create the vortex for the surface of the body and to disperse the vorticity into the fluid area. The motion of the pendulum is determined from Hamilton's principle. The calculated numerical results are compared with the experimental results.
