| Abstract: |
| This paper mainly introduces the advances of studies on navigation lock hydraulics in recent ten years in NHRI.The research achievements in the field of lock filling and emptying system arrangement, lock gate and valve hydraulics, hydraulics of approach channels are presented, especially regarding such new research works as calculation lock hydraulics, unsteady flow characteristics during gate -valve operation, various sudden culvert enlamement behind valves and airvent in valves top seal gap to prevent cavitation etc. All above-mentioned research works are related to large navigation locks of Gezhouba project, Three Gorges project,Wuqiangqi, Shuikou and Shaqikou projects. |
