Abstract
System are provided for internal flow control using plasma actuators. In various exemplary embodiments, a system for fluid flow includes a conduit that contains the fluid flow internally. The conduit has a geometry change through which the fluid flow is channeled. A plasma actuator is disposed in contact with the fluid flow to generate a jet flow in the fluid flow to influence the fluid flowing through the geometry change.

20. A system for fluid flow comprising:
-
a conduit configured to contain the fluid flow internally, wherein the conduit has a geometry change through which the fluid flow is channeled; a plasma actuator disposed in contact with the fluid flow and configured to generate a jet flow in the fluid flow to influence the fluid flow passing through the geometry change, wherein the plasma actuator includes an exposed electrode in contact with the fluid flow, a hidden electrode spaced apart from the exposed electrode, and a patch of dielectric material separating the hidden electrode from the fluid flow and from the exposed electrode; and a power supply coupled with the exposed electrode and the hidden electrode, wherein the power supply includes a power source and a boost converter to increase voltage, and wherein the power supply is configured to supply a voltage to the plasma actuator to generate the jet flow.
