In the hydraulic model test of the CB hydroelectric station in Jinsha River, occasional penetrating vortexes were observed in front of the sluice gate. In order to eliminate the vortex, this paper improved a vertical eddy-eliminating barries and proposed a new horizontal eddy-eliminating barries. The flow field in front of the sluice gate, vortex scale, and vortex generation frequency of the new horizontal eddy-eliminating barries were measured and analyzed for its vortex elimination effect. The results show that the proposed horizontal eddy-eliminating barries has better vortex elimination effect than the previous vertical eddy-eliminating barries, and it is a low-cost and efficient vortex elimination facility for sluice gate.
