Abstract
The Zangao Hydropower Station is located in the plateau area of Xinjiang.The fishway of Zangao Hydropower Station is built for cold water fish.The aspect ratio of the fishpond is 3:2 and the guide baffle is set in left 180°-rectangular curve.The type of fishway is different with a lot of other domestic fishways.The Flow-3d is used to simulate the fishway and the hydraulic characteristics of water flow in single fishway pool and rectangular curves are analyzed.The results show that,(a) the maximum flow rate of vertical joints in fishway pool is up to 1.8 m/s,the turbulence is not violent;(b) in the right rectangular curve,the water flows around the out wall of right curve and the reflow area is large;(c) in the left rectangular curve where the guide baffle being set,the mainstream is in the middle of the curve and the number of return area is increased,the mainstream area is more concentrated and continuous,which is conducive to fish to find migratory routes.The asymmetry of left and right comers and the diversification of the layout of baffles in corners can provide new ideas for the construction of fishways in China.关键词
