Abstract:
1. An electrohydrodynamic (EHD) fluid mover apparatus energizable to motivate fluid flow, the EHD fluid mover comprising: an elongate emitter electrode positioned in a channel at least partially defined by generally opposing surfaces that span at least a substantial portion of a longitudinal extent of the emitter electrode and that extend generally upstream thereof; and a pair of collector electrodes, each spanning at least a substantial portion of a longitudinal extent of the emitter electrode and each having a leading edge relative to the fluid flow, the leading edges positioned downstream of the emitter electrode but each proximate to a respective one of the generally opposing surfaces, the generally opposing surfaces each formed of material suitable for accumulating, over a substantial portion thereof, electrostatic charge conveyed from the emitter electrode and each including a field shaping feature proximate to the leading edges of the respective collector electrode.
