摘要
Abstract
Based on a reconstruction project of a discharge tunnel,a comparative study is made among hydraulic characteristics of ogee discharge tunnels with their intakes on various elevations by a 3-D turbulence model.At first,the reliability of the result from the numerical simulation is demonstrated with the result from the hydraulic model test for the ogee discharge tunnel,and then a comparison is made among four ogee discharge tunnels with the intakes at various elevations in the aspects of discharge capacity,head loss and flow pattern of the tunnel.The result shows that there is no larger impact from the intake elevation on the flow rate,head loss and flow pattern of the tunnel,if all the curved sections of it are ensured to be level and smooth.The study made herein can lay a basis for the design of the discharge tunnel.关键词
