利用计算流体力学（CFD）工具箱OpenFOAM，评估了reynolds -average Navier-Stokes （RANS）解算器在有效波浪中振荡浪涌转换器（OWSC）模拟中的适用性。这些襟翼型装置的仿真需要求解运动方程并在运动网格中表示OWSC的运动。提出了一种新的模拟带移动耗散带的移动网格段内海底的方法。为了评估新求解器的准确性，在一个完整的三维模型中进行了规则和不规则波迹的实验。给出了数值和实验数据的加速度和流动特性计算结果。结果表明，新的数值模型在实验精度范围内能较好地再现实验结果。(C) 2015年作者。Elsevier Ltd.出版。这是一篇基于CC BY许可的开放获取文章。
The computational fluid dynamic (CFD) toolbox OpenFOAM is used to assess the applicability of Reynolds-averaged Navier-Stokes (RANS) solvers to the simulation of oscillating wave surge converters (OWSC) in significant waves. Simulation of these flap type devices requires the solution of the equations of motion and the representation of the OWSC's motion in a moving mesh. A new way to simulate the sea floor inside a section of the moving mesh with a moving dissipation zone is presented. To assess the accuracy of the new solver, experiments are conducted in regular and irregular wave traces for a full three dimensional model. Results for acceleration and flow features are presented for numerical and experimental data. It is found that the new numerical model reproduces experimental results within the bounds of experimental accuracy. (C) 2015 The Authors. Published by Elsevier Ltd.
