The velocity field resulting from vortex flow is studied. The vector field distribution and geometry topology characteristic are discussed by means of numerical simulations.
研究了由涡度诱导出的速度场，采用数值模拟方法，讨论了矢量场的分布和几何拓扑性质。

The secondary velocity vector plots show that the migration of the secondary vortex across the main flow was influenced by flow rates which made the centrifugal and Coriolis force changing.
