Control strategy of cylinder via synthetic jet actuator on separation point

This numerical study is based on the non linear dynamics consociated with synthetic jet with co-existence of circular cylinder. The time dependent fluid interaction, of two dimensional Synthetic Jet Actuator (SJA) is inspected using in-compressible Navier-Stokes equations. To exactly compute the flow due to synthetic jet, the pulsed diaphragm is designed as a moving boundary in a pragmatic mode. The parametric study has been systematized for various sweeps of the diaphragm amplitude and actuation frequency. Performance characteristics and vortex dynamics of the jet extracts interesting flow physics associated with these parameters. The unsteady actuation is able to influence the intrinsic instabilities of separating flows by controlling at lower frequencies. In the current study a detailed parametric study of a simplified configuration is investigated in order to diminution the drag.
