. "The main emphasis of the paper is placed on an effect of an active method of flow control, as a synthetic jet, on a flow field around a cylinder of aspect ratio 1.8. The actuator of the synthetic jet is positioned in front of the boundary layer separation. The principle of a flow control with and without amplitude modulation was used in order to generate lower actuating frequency. An amount of input energy of the actuators that influences the flow filed was measured. A change of lift and drag coefficient was calculated from measured pressure distribution on a model. The alternatives with and without flow control are compared through a relation of saved up and added energy. The influence of basic factors that affect the design of the synthetic jet actuator, particularly the influence of Strouhal number - nondimensional frequency, Stokes number of output orifice, and momentum coefficient are discussed."@en .
