This paper deals with a permanent-magnet induction pump and presents a new numerical model of this pump. The fully coupled transient problem is considered. At each time step, an electromagnetic computation updates the electromagnetic force field in the fluid and feeds it to the transient fluid dynamic computation, which in turn updates the velocity field needed to update the electromagnetic computation at the next time step, and so on. The results obtained with this new model are validated by an experimental study of the recent literature and briefly compared to others numerical models of the literature. This new model has the advantage of being able to predict pressure fluctuations for fatigue analyses and minimum pressure zones for cavitation risk assessment. Tables 2, Figs 6, Refs 12.
