Modelling of a Centrifugal Pump Using the CATHARE-3 One-dimensional Transient Rotodynamic Pump Model

Résumé

The CATHARE-3 predictive transient rotodynamic pump model and its validation in single-phase first quadrant conditions at component scale are presented in this paper. One-dimensional discretization and resolution of governing equations are made according to a mean flow path along all pump parts (suction, impeller, diffuser, volute and discharge pipe), what makes the model original compared to classical 1D models. The model is first verified by comparison to the Euler equation of turbomachinery results. Then, qualification of the model is carried out in steady and transient conditions by comparison to available experimental data. Head and torque characteristics curves are well predicted at different rotational speeds. Finally, a fast startup transient is simulated. Results are satisfactory as the difference between the experimental and modelled non-dimensionalized head is less than 10% of the final value during the whole startup.
