摘要

摘要: 在有限水深下1个漂浮在水中的矩形浮子和1个淹没在水下的浮子构成双矩形波能装置模型。基于特征函数展开法求解了线性入射波作用下双矩形浮子波能装置的辐射问题,得出了双矩形浮子辐射速度势的1种新解析式,然后根据Haskind关系由入射势和辐射势来计算波浪激励力,并且采用数值方法对相同算例进行了计算,得到了完全一致的结果,从而证明这种方法是正确的。研究了在不同工况下的波浪激励力和系统的水动力学系数变化的规律。

Abstract: A system consisting of one floating rectangular cylinder on the free surface and one submerged rectangular cylinder has been applied to a wave energy conversion device in the water of a finite depth. The radiation problem for the wave energy device consisting of dual rectangular cylinders under plane incident wave altim is solved using an eigenfunction expansion method, a new analytical expression for the radiation velocity potential is obtained and then a wave excitation force is calculated by means of the theorem of Haskind that depends on the known incident wave potential and the radiation potential. To verify the correctness of the method, a numerical method is used to recompute the same example, and the obtained results are in good accordance with the analytical method, which shows that the present method is correct. Otherwise using the present analytical solution, the trends of hydrodynamic coefficients and wave force are analyzed under different conditions.
