A novel signal wave pattern is proposed to generate a more efficient synthetic jet; and the unsteady and mean flow characteristics of the synthetic jet generated by different suction duty cycle factors k are examined by numerical simulation. The mean flow-fields of the synthetic jet with different k have similar features to that exhibited in previous experiments; but they would have a stronger and larger scale vortex pair with a larger suction duty cycle factor k; when the two key parameters; the stroke length ratio L0/D and the Reynolds number Reu0 (based on the characteristic blowing velocity U0 and the orifice scale D); are set to be constant. The suction duty cycle factor k affects the vortex strength formed during the blowing cycle only; and nearly does not influence the convection velocity and trajectory of the vortex. During the suction cycle; the entrainment effect of the actuator decreases with the increase of suction duty cycle factor k; so that the vortex pair can propagate farther and coalesce to synthesize a larger scale jet.
