| 摘 要： | 人工鱼礁在海中不同的布局方式会产生不同的流场效应.通过水槽与风洞模型实验很难对组合鱼礁流场全局进行观测,为此提出1种基于CFD原理的人工鱼礁流场特性的计算机数值模拟方法,模拟了不同流速条件下布设间距对方形组合礁体流场效应的影响.结果表明:数值模拟较好地反映了人工鱼礁周围上升流和背涡流的分布情况;当两礁体布设间距为1.5倍礁体尺寸时,所产生的上升流高度达到最大值;当布设间距为1倍/时,其上升流的影响面积为最大;当布设间距为1.5倍时所产生的背涡流效果最好;两礁体之间的最佳布设间距应为礁体尺寸的1～1.5倍.数值模拟结果与风洞实验结果基本相符,该结论可为人工鱼礁实际投放提供理论参考. |

| Abstract: | Effects of flow field around artificial reefs change with the different position mode in sea.It is difficult to carry out model experiment in flume or wind tunnel for observing the whole flow field around artificial reefs.Therefore,a computer numerical simulation method based on CFD was employed to determine the influence of disposal space on effects of flow field around square reefs at different current velocities.The analysis results showed that numerical simulation is a feasible way to study the upwellin... |
