Abstract

Mini turbo-pumps which have a diameter smaller than 100 mm are utilized in many fields. It is desirable that the miniturbo-pump design is as simple as possible due to the limitation of the precision for manufacture. But the design method forthe mini turbo-pump is not established. Therefore, we started the research of the mini turbo-pump for the purpose of developmentof high performance mini turbo-pump with simple structure. It is clarified from the numerical results that head andefficiency decrease drastically with the increase of the tip clearance and the flow condition near the tip region is influencedby the leakage flow from the blade tip. In the present paper, the performance of the mini turbo-pump is shown and the internalflow condition is clarified with the results of the numerical flow analysis. Furthermore, the effects of the tip clearance onthe performance are investigated and high performance rotor design for mini turbo-pump would be considered.
