Abstract
A plasma actuator incorporates a power source, a first electrode in contact with a first dielectric layer, a second electrode in contact with a second dielectric layer, and a ground electrode. The power source drives the first electrode with a first ac voltage pattern with respect to the ground electrode to produce a first plasma discharge, and a first electric field pattern in the flow region, and drives the second electrode with a second ac voltage pattern with respect to the ground electrode to produce a second plasma discharge in the flow region and a second electric field pattern in the flow region. The first and second electrodes are offset along the direction of flow and the first voltage pattern and the second voltage pattern have a phase difference such that the first and second electric fields drive flow in different portions of the flow region at different times.
