摘      要：Mini turbo-pumps having a diameter smaller than 100mm are employed in many fields;automobile radiator pump,ventricular assist pump,cooling pump for electric devices,washing machine pump and so ***,the needs for mini turbo-pumps would become larger with the increase of the application of it for electrical *** is desirable that the mini turbo-pump design is as simple as possible due to restriction to make precise *** the design method for the mini turbo-pump is not established because the internal flow condition for these small-sized fluid machineries is not clarified and conventional theory is not conductive for small-sized *** types of rotors with different outlet angles are prepared for an experiment and a numerical *** performance tests are conducted with these rotors in order to investigate the effect of the blade outlet angle on performance and internal flow condition of mini *** is clarified from the experimental results that head of the mini turbo-pump increases and maximum efficiency flow rate shifts to larger flow rate according to the increase of the blade outlet angle,however the maximum efficiency decreases with the increase of *** the present paper,the performance of the mini turbo-pump is shown and the internal flow conditions are clarified with the results of the experiment and the numerical flow ***,the effects of the blade outlet angle on the performance are investigated and high performance design with simple structure for the mini turbo-pump would be considered.
