Abstract
A synthetic jet ejector (201) is provided which includes a housing (203). A blade (205) is disposed in the housing which has a first fixed end (207) and a second movable end (209), and which is driven by an actuator to trace out a first volume as its free end moves between a first apex and a second apex. The housing has a first portion which is spaced apart from, and complimentary in shape to, at least a portion of the first volume. The spacing (217) between this volume and the first portion is sufficiently small to form a viscous seal around the periphery of the actuator.
