The aim of this paper is to present the analysis of numerical results of the unsteady flow in a spatial turbo-pump stage. This stage includes an axial part with an inducer, and a centrifugal part with a shrouded impeller and a vaned diffuser. The numerical results are obtained with two different softwares that use two different numerical models: a structured model used by Fine/Turbo Euranus solver and an unstructured model used by N3S/Natur solver. Comparisons are performed between the results obtained with these two codes and measurements for steady and unsteady cases. These steady and unsteady studies underline the effects of unsteadiness.
