Experimental study of a hydraulic model of the side inlet and outlet of a pumped storage power station

Abstract Inlets/outlets have bi-directional characteristics and complex structures, which important implications for practical operational safety efficiency. In this paper, the hydraulic of lateral inlet/outlet a pumped storage power station are studied by means model tests. The flow velocity distribution at leading edge orifice barrage section is more uniform, left, middle, right each same. formation swirl related to relative submergence depth s/d Froude number Fr, with Fr < 0.23, > 0.5 it has no harmful eddies.
