The present invention provides a system and method for actively
manipulating fluid flow over a surface using synthetic pulsators.
Synthetic pulsators produce pulsed jet operable to manipulate the primary
fluid flow proximate to the synthetic pulsator. The synthetic pulsator
includes a synthetic jet actuator(s) operable to produce an oscillatory
flow, and fluidic jet(s) operable to provide a continuous fluid flow. The
oscillatory flow of the synthetic jet(s) and the continuous fluid flow of
the fluidic jet(s) combine or mix to produce the pulsed jet operable to
manipulate the primary fluid flow. These synthetic pulsators may then be
actively manipulated to control the flow behavior of the ducted fluid
flow, influence the inception point and trajectory of flow field vortices
within the fluid flow, and reduce flow separation within the primary
fluid flow.
