Abstract

The downstream of a pumped storage power station is equipped with an impedance surge chamber, and the tailrace tunnel is connected with the connecting pipe through bifurcated pipes and bends. The layout type is special, and the water flow conditions are complex. Considering the complexity of the layout of the impedance surge chamber with long connecting pipe and the actual situation of engineering construction, this paper studies the flow pattern and flow coefficient at the bottom of the surge chamber under the typical layout. The variation laws of flow velocity distribution, pressure distribution and inlet and outlet flow coefficient at the bottom of the surge chamber with different layout schemes are obtained.
