本文介绍了一种浮式振荡水柱波能装置的水动力参数计算、建模与仿真。频域水动力参数的计算采用三维面元法。与气室内施加的空气压力引起的波辐射有关的参数是根据互易关系计算的，而不必显式地求解由于施加的压力而产生的辐射势。整个系统的动态特性，包括非线性空气压缩系数和溢流阀特性，以键合图为工具进行了建模。描述了时间域和线性频域模型，并给出了选定的仿真结果，特别是转换后的功率。版权所有©2011，ASME
This article describes the computation of hydrodynamic parameters, modelling, and simulation of a floating oscillating water column wave energy device. The frequency-domain hydrodynamic parameters are computed using a three-dimensional panel method. Parameters related to wave radiation due to applied air pressure inside the air chamber are evaluated from reciprocity relations, without having to solve explicitly for the radiation potential due to the applied pressure. The dynamics of the whole system, including nonlinear air compressibility and relief valve characteristics, is modelled using bond graph as a tool. Both time- and linear frequency-domain models are described and selected simulation results, especially the converted power, are presented.Copyright © 2011 by ASME
