Model experiment for flow resistance characteristics in outlet line well of Baihetan hydropower station

Establishes an experimental model of flow resistance for the outlet line well of Baihetan hydropower station based on the similarity theory. Presents the composition of the flow model testing system and the testing method, and analyses the testing error. Through model experiment, obtains equivalent friction loss factors and comprehensive errors of the outlet line well of Baihetan hydropower station, providing references for the designing and equipment selection of outlet line well ventilation systems of other similar projects.
