摘要
赤道几内亚吉布洛上游调蓄水库底孔泄流时,进口水面出现进气漩涡。为了消除进气漩涡,改善进口流态,通过模型试验对常见的消涡措施进行分析验证。在此基础上,结合工程具体情况,从施工、运行管理及消涡效果等方面进行权衡考虑,推荐采用裹头整体加高到620 m的底孔泄流消涡措施。
When the bottom outlet of Equatorial Guinea Djiploho upstream regulating reservoir discharging , the intake water surface will appear swirl. In order to eliminate the swirl and improve the intake flow pat-tern, this paper analyzes and verifies the common eddy-eliminating measures through model test. Based on this, combing with the specific situation of engineering, this paper takes into account from the aspects such as construction, operation management and eddy-eliminating effect, it recommends the use of bottom outlet eddy-eliminating measure of head wrapped raised to 620 m overall.
