Abstract:
Lateral inlet/outlet is the widely used form of flow transition structure in pumped storage power stations, and is always considered as the throat connecting the reservoir and water pipes. The two-direction flow structure of the lateral inlet/outlet is complicated and affects the operation efficiency and safety of engineering. The reasonable structure type of lateral inlet/outlet is the key to ensuring reasonable flow transition and engineering safety. The methods for studying the shape and hydraulic characteristics of lateral inlet/outlet mainly include physical model test, numerical simulation, and prototype observation. This paper summarizes the research results on the vortex flow, flow transition, and head loss at the lateral inlet/outlet. It analyzes the forming mechanism of vortex, the factors that induce vortex , and the engineering and non-engineering measures to inhibit vortex formation. It defines the engineering requirements of equilibrium transition flow and the structure design criteria that satisfy the equilibrium transition of flow. It also lists the structure parameters, transition flow characteristic numbers, and the water head loss coefficients at the lateral inlet/outlet of some projects.
