| 摘 要： | 基于计算流体力学软件的三维数值模拟技术,分析了碟形越浪式波能发电装置的越浪性能,通过构建基于水气两相VOF(Volume of Fluid)模型的三维数值波浪水槽对该装置进行三维数值模拟研究,数值计算结果与物理试验结果相互对比验证较为吻合,验证了所构建的三维数值波浪水槽的可靠性,通过考察装置的坡度、导流叶片个数、干舷高度对越浪性能的影响确定装置的最优结构参数。结果表明,在装置的斜坡面边缘增加回流板可减少波浪的反射,提高装置的越浪性能。在数值模拟中将装置的斜坡面边缘处安装回流板对碟形越浪式波能发电装置参数进行优化,通过分析回流板的长度对装置越浪性能的影响来探索最优回流板长度。

| Abstract: | The wave overtopping performance of a circular ramp wave energy convertor is analyzed based on the 3D numerical simulation technology used for calculating fluid dynamics. By building up a three-dimensional numerical wave flume used for the VOF (Volume of Fluid) model of water-gas two-phase, a study on three-dimensional numerical simulation of this convertor is carried out. By comparing the results from the numerical calculations and the physical tests, the reliability of the established 3D numerical wave flume is verified. The optimal structure parameters of the device are determined by investigating the influences of the slope number of diversion blades and freeboard height of the device on the overtopping performance. On the basis of all these, a backflow plate is added to the edge of the slope surface of the device to reduce the wave reflection, by which the optimal design of the circular ramp wave energy convertor is studied. The optimal length of the backflow plate is explored by studying the effect of the backflow plate length on the overtopping performance of the convertor. |
