Abstract
A plasma plate is used to minimize drag of a fluid flow over an exposed surface. The plasma plate includes a series of plasma actuators positioned on the surface. Each plasma actuator is made of a dielectric separating a first electrode exposed to a fluid flow and a second electrode separated from the fluid flow under the dielectric. A pulsed direct current power supply provides a first voltage to the first electrode and a second voltage to the second electrode. The series of plasma actuators is operably connected to a bus which distribute powers and is positioned to minimize flow disturbances. The plasma actuators are arranged into a series of linear rows such that a velocity component is imparted to the fluid flow.

A plasma plate comprising:
- a plurality of plasma actuators positioned on a surface, each plasma actuator comprising:
- a dielectric;
- a first electrode exposed to a fluid flow;
- a second electrode separated from the fluid flow by the dielectric;
- a pulsed direct current power supply providing a first voltage to the first electrode and a second voltage to the second electrode;
- and
- a bus operably connected to distribute power to the plasma actuators, positioned to minimize flow disturbances, wherein:
- the plasma actuators are arranged into a series of linear rows such that a velocity component is imparted to the fluid flow, and
- the exposed electrode is adapted to produce opposing spanwise blowing with a stagnation line in a space between neighboring covered electrodes.
