  • SYSTEM AND METHOD FOR REDUCING WAKE
    Publication number: 20080149205
    Abstract: A machine includes an unsteady blower device, such as a synthetic jet actuator, disposed such that an aperture of the blower is disposed upon the trailing edge of the machine component. The unsteady blower device is actuated to perform unsteady blowing of a fluid from the aperture in order to enhance turbulent mixing in the flow to mitigate undesirable wakes that interact with downstream components. Such unsteady blower devices facilitate momentum transfer or unsteady excitation or energy addition into the flow through the machine via direct injection of additional fluid.
