Comparative Test and Study on the Area of Flow Regime Influenced during Flowing around Various Pile Clusters

Abstract

By comparative testing and studying and analyzing on the area and range of flow regime influenced during the uniform water flow with free surface and definite depth flowing around varied pile clusters, The author had found and summarized and concluded many scientific laws, which of flowing around pile cluster effect on the uniform water flow, the natural and extents disparity of varied pile cluster effect on the same uniform water flow, the area and range of flow regime influenced during flowing around varied pile clusters. And had found that the influenced extent and scope of flowing around square pile cluster effecting on the uniform water flow more than that of cylinder pile cluster. For a pile cluster, in the way of influenced extent and scope of flowing around the pile cluster, the ratio of obstruct the water flow more than the density of pile lines, and Reynolds number influence the extent and scope of flowing around pile cluster in big degree. It is even more superiority that people adopt the small size pile than the big size pile about pile cluster on water conservancy project.
