英文摘要：

A series of hydraulic model experiments and 3-D numerical simulation of water flow and head losses of lateral inlet/outlet under various conditions were carried out for the design of a pump-storage plant. The primary form was successfully optimized to make hydraulic parameters ideal. The mathematical calculation adopted RNG κ-ε turbulent model and multiply sub-districts method. The coupling numeration of velocity field and stress field was based on SIMPLEC. The calculation results accorded with the experimental data. By optimizing guide piers, top board and sidewall, the main problems of asymmetric water flow and great head losses in the lateral inlet/outlet of pump-storage plant were resolved.
