résumé A dimensionless analysis of a centrifugal pump transient, based on experimental results of various start-ups of this pump is proposed. It is based on the comparison of transient and steady terms coming from global moment of momentum and energy equations applied to an impeller or on a local analysis of the acceleration of a fluid particle inside an impeller in transient operations. Both methods give reliable criteria characteristic of the rapidity of a start-up.
