摘要
人工鱼礁流场流态效应的研究,是鱼礁结构设计的重要理论依据,为此提出一种基于CFD原理的用于预测人工鱼礁流场效应的数值模拟方法,模拟了星体型鱼礁在水中两种不同的摆放形式下的流场效应。结果表明,数值模拟能够反映人工鱼礁流场效应,当鱼礁轴线与流向垂直时流态较好,与理论分析结果基本相符。
It is an important theory basis for artificial reefs design and calculation to study the features of flow field around reefs.Therefore,a CFD method was employed to determine the features of flow field around reefs,and the flow field around star reefs of two different positions was simulated.The results of numerical simulation that accords with analysis show that the computer simulation can reveal the feature of flow field and the features of flow field around reefs are better when the axes is perpendicular to the current.
