圆柱桩群绕流特性试验研究

通过水槽试验,研究了不同圆柱桩群对均匀水流绕流流态的影响程度,对比分析多组试验研究数据发现了:圆柱桩群对均匀水流的影响规律,不同圆柱桩群对同样水流影响性质与程度的差别,不同圆柱桩群对水流流态影响范围的规律,圆柱桩群的阻流率、排架密度和桩群长度对水流流态的影响规律,不同流速水流对圆柱桩群绕流流态影响规律.得出结论:桩群阻...

Study on Characteristics of Circumferential Motion of Cylinder Pile Cluster

By flume test on the effect degree of different cylinder pile cluster on the flow regime of uniform water flow,and contrastive analyzing the several series of experimental data,we have found the scientific law of cylinder pile cluster effect on the flow regime of uniform water flow,the nature and extent disparity of different cylinder pile cluster effect on the same uniform water flow,the scientific law of affected scope of the different cylinder pile cluster of the flow regime of uniform water flow,the scientific law of the flow resistivity,the density of cylinder pile lines and the length of cylinder pile cluster effect on the water flow and the scientific law of the effect of different uniform water flow with various velocity respond to cylinder pile cluster.Moreover,we concluded that the drag of cylinder pile cluster was one but not the only one factor which influenoed the water flow.The arranging formats and up-flow angles of cylinder pile cluster had different degree of effects on the flow regime of water flow.And the eflects of these two factors were larger than that of the drag.
