1. 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.
