摘要：
In this paper, the streamfunction-vorticity formulas of Navier-Stokes equation are discreted by finite element approximations. At different step ratios, the forming and developing of the recirculation zones and the final vortexes structure have been shown schematically. The streamline patterns, the vorticity contours and the velocity vector plots have been given in order to know the flow field dearly. It has important significance for us to analyze the energy loss and design the step ratio properly.
