多浮摆式采能装置的水动力学模拟

Hydrodynamic simulation of multi-pendulum wave power converter

多浮摆式采能装置是利用多块浮摆采集波浪能的新型波浪能发电装置。文章基于三维频域势流理论,采用数值模拟方法计算了多浮摆和单浮摆的水动力性能,并分析了浮摆间距对多浮摆水动力性能的影响。结果表明,多浮摆间的相互作用会产生异于单浮摆的共振峰值,间距对多浮摆的水动力影响呈现先增大后减小的趋势。

Multi-pendulum wave power converter is a device for better ability to capture wave energy by taking advantage of its multi-pendulums. Hydrodynamic performances of a multi-pendulum system and a single pendulum system are examined in this study, using numerical simulation on the three-dimensional potential theory and considering different gap sizes of pendulum. The results show that in a multi-pendulum system, the interaction of its multi-pendulum produces resonances of peak values different from those in a single pendulum system, and that as the gap size increases, its influence on hydrodynamic performance takes a trend of first increasing then decreasing.
