| Abstract: | This paper presents the expression reflecting vortex evolution under the assumption of being slowly divergent. The characteristic of the solution has been analyzed. The bubble region andvortex breakdown appear under certain conditions.The effects of the divergent angle and rotational velocity on the location of the vortex breakdown arediscussed. |
