Abstract
The mini centrifugal pump is widely used in the fields of industry and medical science, such as the cooling system of the fuel cell and the high-performance PC, and the ventricular assist device. Further downsizing and energy saving is required, and the investigations related to the internal flow is necessary in order to enable the high pump performance. In this research, the splitter blades are installed to the impeller of the mini centrifugal pump. And the splitter blades length is changed to research the influence of it on the performance and internal flow. The performance test was conducted by the experiment and numerical analysis. Furthermore, the internal flow was investigated by numerical analysis.
