摘要
针对滑动挡板斜坡堤式波浪发电装置,通过模型试验和数值模拟,研究斜坡比对装置越浪量的影响以及水深、滑动挡板顶高程、泄流通道直径等对泄流通道内流速和能量转换的影响。研究结果表明,相同水深条件下,斜坡堤的最优斜坡比为2.0。相同水深和斜坡比时,泄流通道内流速随滑动挡板顶高程的增大而减小。通过调整滑动挡板顶高程与水位的关系及优化流道内径,该发电装置在试验中的稳定获能系数可达到约8.0%。
Aiming at sliding plate breakwater type wave energy power generation device,the effect of slope ratio on wave overtopping discharge of the device and influence of water depth,height of sliding plate’s top,diameter of flow channel etc on flow rate and energy conversion in flow channel are studied through model test and numerical simulation.The results show that the best ratio of slope is 2.0 when water depths are same.Under the same condition of water depth and ratio of slope,the flow rate in flow channel decreases when height of sliding baffle’s top increases.By adjusting the relationship between height of sliding plate’s top and water depth and optimizing the inner diameter of the flow channel,the steady energy capture coefficient of this device can reach about 8.0% in the experiment.
