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