In order to clarify the influence of different turbulence models on the numerical simulation of the pump turbine, 3D numerical steady simulations using four kinds of turbulence models: SST, k-ε, k-ω and RNG k-ε were applied to simulate the flow inside the mixed-flow pump turbine. 16 monitoring points were installed in guide vanes to obtain the relationship between pressure distribution of guide vanes in different monitoring locations and operation conditions. The pressure distribution of guide vanes was simulated using four kinds of turbulence models, and compared with the model test results. The results show that when the turbulence model is SST, the numerical simulation results are closer to the model test results.
