| 摘 要： | 本文根据特征函数加源分布、内外域拟合的方法,建立了振动水柱港池系统的三维理论模型。计算了气室水面振荡的频率响应函数、不规则波中的统计值,以及系统的最大吸收宽度比。论讨了不同港池长度、不同阻抗规律对气室水面振荡的影响。结果表明,不同阻抗规律对气室水面的振荡有显著影响。与现有结果比较指出,如不考虑阻抗规律的非线性性质,势将低估其性能。

| Abstract: | A 3-D theoretical model of an OWC with a harbour system has been presented,based on the method of eigenfunction,source distribution and matching the inner region with outside.The response of the OWC in frequency,its statistical value in an irregalar wave and an optimum capture-width ratio of the system has been calculated.The influence of the harbour length and the impedance on the oscillation of water surface in the chamber is discussed.The results show that the influence of different impedance on the oscillation of water surface in the chamber is considerable.In comparison with the existing results,it is found that the performance of the system will be underestimated,if the nonlinear characteristic of the impedance is not considered. |
