Abstract
Mini turbo-pump is used in a wide range of fields, such as water-cooler for personal computer, fuel cells, and ventricular assist device. And there is demand for more compact and higher performance. But the design method for the mini turbo-pump is not established because the internal flow condition for the small-sized fluid machineries is not clarified and conventional theory is not applicable to small-sized pumps. In this study, the impeller having large blade outlet angle and splitter blades was designed and manufactured. The performance test was performed by the experiment and the numerical analysis. From the results, the performance and the internal flow were investigated about the rotor with and without splitter blades.
