چکیده
|
Based on the active control theory, the synthetic jet behind the blunt body is explored by considering the control of flow around the blunt body in this paper. the partially averaged navier-stokes model was carried out for flow around circle cylinder at two subcritical reynolds numbers (re=1000, 3900), whose results have a good agreement with the experimental data. the results indicate that synthetic jet behind the circle cylinder has essential effects on the vortex shedding of flow around circle cylinder. the analysis of the vorticity and q vortex shows that the increasing velocity of synthetic jet has a strong effect on the vortex shedding of the original flow field. it is noted that the information including the coherence data and the directivity pattern with the existence of synthetic jet is different from that without synthetic jet. these results imply that the synthetic jet in the tail of the blunt body could control the flow fields around the blunt body.
