Study on the Flow Field Characteristics of Fishway in a Water Conservancy Project based on Physical Model Experiment
Physical model experiment is carried out for the fishway in Feilaixia Water Conservancy Project.The flow ve-locity,time-average pressure,and turbulent energy distribution of each section of the fishway under different flow rates and openings are obtained.The results show that the peak flow velocity mainly occurs in the second stage fishway.The maximum time-average pressure occurs at the outlet of the fishway.The variation of the turbulent kinetic energy of each stage fishway is relatively stable.The adjustable gate of the fishway is of a good control effect on the water flow turbu-lence.The results provide useful reference for the design of fishways.
