| 摘 要： | 使用废旧轮胎对海漫进行柔性加糙,是提高消能防冲效率的有效方法。通过水工模型试验,量测了加糙后三维流速的分布情况,并计算出水流质点的三维相对紊动强度和雷诺应力,分析其变化特征。结果表明:海漫加糙后,表层水流的紊动强度和雷诺应力最大,两者具有相似的分布特征。

| Abstract: | Application of scrap tires is an effective approach to increase the roughness of apron and improve efficiency of energy dissipation.Based on hydraulic model test,the distribution of three-dimensional velocity was measured.The three-dimensional relative turbulence intensity and Reynolds stress of water particles were calculated,and their variation characteristics were analyzed.The results show that the turbulence intensity and Reynolds stress of surface water are the maximum and their distribution characteri... |
