倒V形阶梯与传统阶梯流场特性对比研究
Comparison of the flow field in inverted V-shaped and traditional stepped spillway
摘要
Abstract
Inverted V-shaped stepped spillway is a new shaped stepped spillway,which has unique flow characteristics.In order to study the unique flow field characteristics of inverted V-shaped stepped spill-way,a comparison study on flow velocity distribution,pressure distribution and energy dissipation charac-teristics was made by numerical simulation between the inverted V-shaped and traditional stepped spill-ways,based on the model test research.The result shows that the flow structure and the pressure distri-bution between inverted V-shaped and traditional stepped spillways are quite different,these distributions have obvious differences along the cross section with unique three dimensional characteristics.It has bet-ter energy dissipation rates in inverted V-shaped stepped spillway than that of in traditional stepped spill-way.关键词
