    This research aimed to establish a numerical analysis method for use in commercial CFD packages to evaluate a pump-turbine with different guide vane openings. Additionally, this study proposed an appropriate numerical method to investigate flow characteristics. A three-dimensional steady-state Reynolds-averaged Navier-Stokes (RANS) equation was solved to evaluate the internal flow characteristics in the turbine mode. A combination of a grid system, turbulence model, interface position, and interface condition is crucial for the effective prediction of the hydraulic performance of the pump-turbine. The reliability of the numerical analysis method was demonstrated by comparing numerical and experimental results. The error range of the reliability verification of the frozen rotor and stage average was approximately 1.5% -2.5% at the design flow rate. Overall, the numerical results indicated a high predictive power with high reliability within the operating range.
