The turbulent mixing effect of water flow at the intersection of pipelines is strong,and the energy loss of water flow is great,which affects the flow capacity.The study simulates the hydraulic characteristics of intersecting pipe sections under different working conditions with the finite volume method,discusses the hydraulic parameters such as the flow rate of the cross pipe network,and reveals the hydraulic characteristics and the influence of design parameters on the cross pipe network.The results show that with the increase of the inlet angle,the influence of the inlet angle on the interchange velocity is more and more obvious,and the maximum reaches 90°.With the increase of the confluence ratio,the tributary water compresses the main stream significantly,which affects the overflow capacity.The results can provide a basis for pipe network optimization design and operation management.
