AB - In this research, a methodology based on the development of numerical simulations is
proposed to analyze the physical behavior of centrifugal pumps such as a turbine. Numerical
simulations were carried out using OpenFOAM software. For the validation of the numerical
model, the construction of an experimental test bench was carried out. The analysis carried out
involves the evaluation of performance parameters of the pump as a turbine, such as head, power,
and efficiency. Additionally, the effect of the rotation speed on the previous parameters is
evaluated. From the results obtained, it was shown that the maximum relative error was 4%,
3.4%, and 3.8% for the head, power, and efficiency parameters, respectively. In general, it was
evidenced that the proposed numerical simulation has the ability to describe the real trends of
the pump as a turbine for different flow conditions. In addition, an 11% increase in rotational
speed was shown to cause a 12%, 1.9%, and 3% increase in head, power, and maximum
efficiency. The proposed methodology is considered an adequate tool to analyze performance
and identify the best efficiency point of pump systems such as a turbine. In this way, greater
energy use is guaranteed.
