Abstract
A surface plasma actuator includes a conducting wire attached to a surface of a target object and electrically insulated from the target object. Surface plasma is generated along a neighborhood of the conducting wire by applying a pulse voltage between the conducting wire and a conductive portion on a side of the target object. An induced gas flow is generated by the surface plasma.
Claims18
A surface plasma actuator, comprising:
- an electrode attached to a surface of an insulating target object and formed from a conductive thin film or thin plate;
- and
- an insulation coated conductor attached to the surface and disposed opposite the electrode along a lengthwise direction, the insulation coated conductor comprising a conductive wire and an insulation material coating, wherein
- surface plasma is generated between the insulation coated conductor and the electrode by applying a pulse voltage between the electrode and the conductive wire, and an induced gas flow is generated by the surface plasma.
