Contribution to the Study of a Flow Controlled by a Synthetic Jet

Abstract:

Active control of flow over a cylinder at Re=1800, based on the free-stream velocity U∞=0.67m/s, and cylinder diameter d=40mm, is carried out using a synthetic jet. The slot injectors are positioned at θinj = ± 70°. An actuator was used to produce a synthetic jet by exciting a cavity with an alternative piston system. The results show that for the frequency of control located around the natural frequency of the vortex emission a phenomenon of lock-in appear.
