摘要
基于特征函数展开法,求解线性入射波作用下双矩形浮子波能装置的散射问题,得出绕射速度势的一种新解析式,并由绕射势和入射势计算出波浪激励力。采用边界元数值方法对相同算例进行计算,结果可验证该文方法的正确性。研究探讨了双矩形浮子波能装置浮子间距对浮子波浪力的影响。
Firstly, by use of an Eigen function expansion method the scattering problem for the wave energy device consisting of dual rectangular cylinders due to a plane incident wave was solved, a new analytical expression for the diffraction velocity potential was obtained and then the wave excitation force was calculated by the known incident wave potential and the diffraction potential ; Secondly, to verify the correctness of the method, a numerical method was used to recomputed the same example and the obtained results were in good accordance, which shows that the present method is correct; lastly, the wave force properties with distance of the dual rectangular cylinders were studied.
