主　　题：plasma flow control tri-electrode sliding discharge particle image velocimetry(PIV) performance evaluation 

摘      要：Tri-electrode sliding discharge(TED)plasma actuators are formed by adding a direct current(DC)exposed electrode to conventional dielectric barrier discharge(DBD)plasma *** are three TED modes depending on the polarity and amplitude of the DC supply:DBD discharge,extended discharge and sliding *** paper evaluates the electrical,aerodynamic and mechanical characteristics of a TED plasma actuator based on energy analysis,particle image velocimetry experiments and calculations using the Navier-Stokes *** flow control performances of different discharge modes are quantitatively analyzed based on characteristic *** results show that flow control performance in both extended discharge and sliding discharge is more significant than that of DBD,mainly because of the significantly higher(up to 141%)body force of TED compared with ***,conductivity loss is the primary power loss caused by the DC polarity for TED ***,power consumption can be reduced by optimizing the dielectric material and thickness,thus improving the flow control performance of plasma actuators.
