| 초록 | The effect of streamwise vortices generated from passive vortex generators was investigated to manipulate the separation bubble behind the vertical fence.The experiments were carried out in a circulating water channel and the velocity fields were measured using 2D and stereoscopic PIV method.The distance between the vortex generator and fence and the effect of the Reynolds number were investigated.In addition,the effect of boundary layer thickness was also investigated.The averaged recirculation lengths were compared with that of uncontrolled fence flow.The results showed the oscillatory variation of recirculation region appeared under the existence of vortex generators.The reduction of the separation bubble became larger when the fence was submerged in the thick boundary layer with increasing the distance between the generator and fence.When the boundary layer is thin,vortex generator can only suppress the separation bubble under the specific condition. |
