| Abstract: | The swirling flow in slowly divergent ducts is investigated. The stream function equation and zero-order analysis solution are presented. Equations for velocity distributions of four initial flow patterns of practical value are given. From calculational results, it is discovered that under certain conditions the reverse flow, causing vortex breakdown. |
