- 論文の詳細を見る
Velocity profiles of the laminar flow in the developing region of an axially rotating pipe are analyzed numerically in this paper and compared with the experimental results obtained when a uniform axial flow is introduced. It is found that the axial velocity in the rotating pipe exceeds the value of the Poiseuille flow at the center, and that a backward flow appears near the pipe wall as the rotation rate becomes large. The greater the rotation rate N becomes, the more remarkable the excess of the axial velocity at the center and the backward flow near the wall tend to become ; experiments show, however, that at about N=3, pipe rotation causes the flow to become unstable and the development of the flow is delayed.
