| Abstract: | Discussions are made in this paper about the definiens of boundary layer of buckets. The conceptions of the boundary layer thickness caused by the centrifugal force and wall roughess are suggested based on the analyses of velocity distributions of buckets, and some effects of wallcurvature and wall roughness on the boundary layer development of buckets are shown. |

| Keywords: | bucket definiens of boundary layer added boundary layer thickness of centrifugal force and roughness |
