PREDICTION OF BREAKDOWN LOCATION OF SLOWLY DIVERGENT VORTEX

摘要: 在慢扩张的假设下给出一类旋涡发展的解析表达式，讨论了解的性质．在一定情况下会出现泡型区和涡破裂．讨论了扩张角及旋转速度对涡破裂位置的影响．

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.
