| Outline of Final Research Achievements |
The generating mechanism of unsteady hydrodynamic force, the generating mechanism of loss, and the blockade mechanism of foreign bodies based on the complicated unsteady internal flow of a closed type and an open type single-blade centrifugal pump which are used as a sewage pump were investigated from both sides of an experiment and a numerical analysis. As a result, the difference which arises in the single-blade centrifugal pump of the closed type and the open type about unsteady hydrodynamic force and loss was clarified. Furthermore, the passage examination of foreign bodies and the visualization experiment were conducted, and the passing probability of the closed-type centrifugal pump with single blade and the action of foreign bodies were clarified.
