Research on Eddy-eliminating of Equatorial Guinea Djiploho Upstream Regulating Reservoir Bottom Outlet

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 pattern，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.
