Three-dimensional numerical simulation on inlet/outlet of pumped storage station

摘要

The paper has numerically simulated the inlet/outlet of a pumped storage station based on the wall of the law of RNG k-e turbulence model. The head loss coefficients between gate shaft and inlet/outlet, in the lower bending section, and the distribution of velocity in each flow passage channel were simulated. The comparison between the numerical results and the data of physical model test verified the reliability and accuracy of RNG k-e turbulence model, Simulation results shows that the method applied in this paper is convenient and quick, and could achieve high precision.
